Leave a reply

Stripping cables is one of the processes in wire harnessing, besides cutting and crimping processes.

There are many ways to strip a cable, from using the conventional cutter to using the manual/automatic wire stripping.

There are some basic points we need to know in doing the stripping process.

  1. Cable size
  2. Stripping length

Choosing the correct tool and setting the correct stripping length will produce the perfect stripping result for crimping process.

Manual Stripping Tool

With manual stripping tool, there are some concerns such as fatigue, consistency of stripping length and time.

Automatic Stripping Tool

All the concerns with manual stripping tool can be solved with the Automatic Stripping Tool.

Phoenix Contact knows this and has developed automatic Stripping Tool called WF 1000.

With this automatic device, we can strip cables without any fatigue, get the precise length and it takes only 0.3s per process.

This machine will boost your productivity with high quality output.

Features:

  1. This compact stripping machine automatically insulates conductors with a cross section of 0.08 to 6 mm2.
  2. Multi-strand cables with a diameter of up to 6 mm are also stripped.
  3. Partial stripping is supported.
  4. Special insulations such as PTFE and silicone can be stripped, in addition to standard insulations
  5. The clamping force automatically adjusts itself to the required extraction force. This reduces/prevents pressure points on sensitive insulation.
  6. The stripping dimensions are set individually via rotary buttons. They are shown on the clear display.

Over the past decade, we have done quite a number of seminars, but the Philippines’ Energy Day seminar concluded last Nov 22, was truly a successful one. Highlighting on the success was the jam-packed seminar room hitting more than 100% of the expected attendees, smooth registration, and attentive, lively and participating audience. I can’t say anything more but an unfading thanks to the speakers Gary and James, PxC PH team, Marcom team, IMAXX team, and of course to all the companies, guests and attendees who have lent their ears on these upcoming trend topics in the Philippines, which are Surge Protection and IEC 61850.

Clearly shows a very satisfied crowd and thumbs up on our two great speakers. This had made up my mind to repeat this success and to conduct Energy Day Part 2.

Planning for Lightning and Surge Protection?

From |
Leave a reply

Choosing the right Lightning and Surge Protection is a lifelong investment, just like purchasing a good comprehensive life insurance policy. Without proper planning and consideration, your business, your home maybe inadequately protected and most importantly your people/investments will be at risk.

In this article we shall dive in on the risk assessment, lightning and surge protection zoning and protective devices type.

A point to note: As you may know, Surge Arresters are vital when you are planning for a lightning and surge protection system. For information on when Lightning and Surge Protection is necessary, visit our previous article here.

Three points to consider when planning for Lightning and Surge Protection: 

  1. Risk analysis with accordance with IEC 62305

The answer to the common question: “Do I need to install lightning and surge protection devices?” boils down to the result of a careful and systematic risk assessment, which is carried out after inspection of the physical structure and electrical installation.

It would start with addressing the risk of various sources of damages (e.g. a direct lightning strike in the building, transient overvoltages that are coupled into the electrical installation caused by atmospheric influences) which come into focus, as do the types of damage resulting from these incidents:

  • Impact on health or loss of life
  • Loss of technical services for the public
  • Loss of irreplaceable objects of cultural significance
  • Financial losses

The financial benefits are determined as follows:

  • How does the total annual cost for a lightning protection system compare to the costs of potential damage without a protection system?
  • The cost evaluation is based on the expenditures for the planning, assembly, and maintenance of the lightning protection system.

If the risk assessment determines that lightning and surge protection is required, then the type and scope of the specific measures for protection to be considered will include:

  • External lightning and surge protection
  • Internal lightning and surge protection
  • Grounding and equipotential bonding
  • Coordinated Lightning and Surge Protection Devices system
  1. Characterizing the lightning protection zones (LPZ)

In order to ensure the total protection of a physical structure from the effects of lightning strikes and surge voltages, various protective measures or equipment that are tailored to one another are required.

The installation locations of surge protective devices within a physical structure are determined using the lightning protection zone from part 4 of lightning protection standard IEC 62305.

It divides a physical structure into lightning protection zones (LPZ), and does so from outside to inside with decreasing lightning protection levels. In external zones only resistant equipment can be used. However, in internal zones, sensitive equipment can also be used. The individual zones are characterized and named as follows:

  • LPZ 0A: Unprotected zone outside of a building where direct lightning strikes are possible. The direct coupling of lightning currents in cables and the undamped magnetic field of the lightning strike can lead to danger and damage.
  • LPZ 0B: Zone outside the building that is protected from direct lightning strikes, for example, by an air terminal. The undamped magnetic field of the lightning strike and induced surge currents can cause hazards and damage.
  • LPZ 1: Zone inside the building where high energy surge voltages or surge currents and strong electromagnetic fields are still to be expected.
  • LPZ 2: Zone inside a building where surge voltages or surge currents and electromagnetic fields that have already been significantly weakened are to be expected.
  • LPZ 3: Zone inside the building where surge voltages or surge currents are expected to be only extremely low or entirely absent and electromagnetic fields are expected to be only very weak or non-existent.

Lightning protection zone concept with coordinated SPDs at the respective zone transition points

  1. Lightning and Surge Protection Device types

The lightning protection zone concept provides coordinated surge protective devices for all cables that cross between zones. Their power values are based on the protection class to be achieved. As such, different SPDs are required based on the zone transition points.

 

The requirements for the individual SPD types are defined in the standard IEC 61643- 11 [6] for surge protective devices used in low-voltage systems. A multi-level protection concept is derived from this:

Risk assessment, in general, is a complicated and demanding process. An advisable starting point is to list out the areas that are most at risk and filter to the ones that are not.

Once you’ve listed out the potential risk areas, you can then consider the types of SPD best suited to the kind of application/equipment you’re protecting.

Food for Thought: Lightning strikes 90% of the earth. Some parts are highly prone to lightning strikes while some aren’t.

Since Southeast Asia sits comfortably near the equator, the hot and humid weather makes conditions favourable for the development of lightning producing thunderstorms. Thus, it is important to make sure you are well-protected.

Other tips for Risk Assessment

Be sure to refer to risk assessment standards IEC 62305-2. Some countries make it compulsory to use the standard when considering surge protection for large scale or highly sensitive buildings such as industrial facilities, hospitals, and data centres.

7 Habits of Highly Effective People (Part 1)

From |
Leave a reply

Do you sometimes feel lousy, sluggish and lethargic? Recently, I was telling myself, “Hey, I need to do something to better improve my mind-set and be more productive”.

One fine afternoon as I was walking past our in-house library shelf, a prominent book caught my eye, “The 7 Habits of Highly Effective People” by Stephen R. Covey. I picked it up and, deciding to step out of my comfort zone, started reading.

There are 3 parts to this book, and in this series of blog articles, we will be covering part 1. It speaks of the private victory that needs to be inculcated as a personal habit. Private victory means to have self-mastery in our personal life and to become independent with 3 pointers, the first of which is shown below.

  1. Be Proactive

Imagine 2 sales people, one of middle age who is only ever complaining about how tough it is to do sales today and how customers are ever demanding and always comparing prices. Moreover with the high cost of living, the stress level is overwhelming. His habit: always reactive.
The other, a young chap who understands and seeks to improve the situation by finding ways to gain more commission from his sales, in order to generate passive income to better provide for his family. His actions: always proactive.

Being the first guy is the easy way out, it requires less effort and all that is needed is to be negative and compliant. On the other hand, being the young chap requires the spending of countless hours to understand the customers, to propose solutions to upsell to them and research on the best options that can allow him to make passive income to the best of his abilities.

Responsibility – ‘response ability’ is the ability to choose your response. With this ability, the freedom to choose based on self-awareness, imagination, independent will and conscience, our proactive response will be determined.

Recently, taking over a key customer from the previous sales person, there were many gaps and unknowns such as:

  • No customer part number tag to manufacturer part number
  • No project names of existing orders
  • No project names of upcoming models
  • Uncertain about the allocation of the awarded parts.
  • No annual usage
  • No account plan

Two options were available, to sit there and complain about the missing information and put the blame on everyone else who is and was involved for not doing a good job, or to take the initiative to go to the customer and fill up the gaps and missing information.
Coming up with a proactive plan in mind to understand the customer, giving customers the assurance and security that we are interested in their business and to provide the best support that they can get, is the game plan.
It is not an easy path, but the rewards will be reaped after we sow the seeds.

Finally, I will leave you with some food for thought.

Stay tuned for the other 2 habits in my future blogs.

Weight Loss

From |
Leave a reply

Recently, the people that I know have been asking what actually happened to me. For some who have known me long enough, my weight previously almost hit the 100kg mark and now I am 79kg. What caused the tremendous loss of weight? Some ask if it is because of stress, if it is because of health issues. Some even ask if it is because I’m having a new girlfriend. Well, the actual answer is simple, I just want to look & feel good.

Slimming down is actually simple. There are actually 2 ways of slimming down, the conventional way and the simple way.

The simple way is what we have heard of in recent years, where you need to purchase certain slimming products and consume it. There are some products which claim that you can slim down without even doing workouts. This method usually will cost you a bomb and the results are sometimes uncertain.

The conventional way is rather what we have heard since the old days. This way is basically to exercise, practice diet control, etc. The conventional way is being known as the “hard way”, but this costs less and will take a lot of hard work.

Well, personally I choose the conventional way. The reason is very simple – I don’t want to spend much money on losing weight. I would rather spend the money elsewhere.

The first thing you need to do is to control your diet. You need to know what is the recommended daily calorie intake for a man/woman. Then, you need to know the estimated amount of calories of the food you consume. Bear in mind that most food manufacturers do state the calories/100g. If it is not stated or the food you consume is from your local hawker stall, you can actually search online as someone might have done research before. From there, you can do your own calculation on how much you consume every day. This method will usually allow you to just maintain your weight or maybe lose some of it.

Next up is the most important factor in losing weight. We must be clear on how much intake we have and ensure that these calories can be burned. Most of us who are working in the corporate world will have very limited movements daily. Hence, the amount of calories burnt is less than the calories consumed. Exercise is the way to burn calories & fats fast. Apart from burning calories, regular exercise makes you feel more energetic and young. Personally, I do only 2 sessions of exercise per week, 2 hours of basketball & futsal each. During the session, I personally set a target of the amount of calories to be burnt. If this target is not met, I will immediately find an alternative way to burn calories, for example, by jogging.

Finally, I think discipline is what makes it happen. We know that we need to control our diet and exercise but how many of us are able to do it consistently? We must remember we don’t get fat in one day and same goes for losing weight. All of us know what has to be done to lose weight but we are just not disciplined enough to do it consistently.

Teams and Team Dynamics

Leave a reply

Have you ever wondered why do teams exist?

Let us begin with the definition of the word “Team” as a noun.

“A number of persons forming one of the sides in a game or contest; a number of persons associated in some joint action.” (Dictionary.com)

Teams are present almost everywhere in this world that we are living in. We can see teams being formed in the work place, sports, games, social organizations, government etc.

No team is similar, as every team consists of members with different attributes and personalities. The difference lies in how the members of the team contribute to meet the goals and objectives set, in the most efficient manner. As there is no exact clone to every individual, members of the team have to understand one another’s strengths and weaknesses. By understanding the strengths and weaknesses of our peers, we will be able to make use of their individual skills strategically to work towards the objective. A good team would consist of members with different skillsets, say for example in a soccer team. If the whole team of 11 players is made up of strikers, no one will be on the field to defend the goal post, and neither there will be anyone to create chances for the strikers. This gives us an understanding on the importance of selecting the right people to join the team before anything else, to ensure that every member has a relevant skill that will help in one way or another in reaching for the team goal. Teams need a healthy mix of individuals to get things done, and know who is best suited for the tasks and how to best accomplish them.

With a group of individuals working towards a goal, is there be a need for someone to guide, nurture, and devise strategies for the members? The answer is a definite yes. This is where the role of a leader comes into place. The basic role of the leader will be to communicate and plan work for the members of the team, even before any actions are taken by the rest of the members. The leader will also have to motivate and guide the members, so that the members are passionate towards the work that they are doing, and also to stay on the correct track towards the team goal. There isn’t a single team without a leader, as there will be no co-ordination nor strategies implemented by the team, which will lead to problems, conflict, inefficiency, and in the worst case, not achieving the team’s target.

As a rule of thumb, a team’s setup is of utmost importance, and every member has to work effectively and dynamically in order to win. At Phoenix Contact, we collectively select the action steps our teams take, to unlock our full potential. Team goals have been identified before any member starts doing the work. Conflicts are avoided by development of plans and constant communication within the teams. Our team dynamics enhance productivity and accomplish goals, where everyone in the team talks and listens. Last but not least, we have reliable team leaders to lead the members and head towards our goals.

Let us all strive to work hard, and play hard, as both an individual and as well as a team. In the case of Phoenix Contact, to win as a team would be to win our customers’ trust.

Lightning Protection Systems

Leave a reply

Lightning is the process of discharging the electrical charge in a cloud. Lightning energy released can produce a series of light, heat, and a very strong sound, it can damage buildings, kill humans, blow up trees and impair electrical equipment. The average speed of lightning is 150,000 km/sec and it usually arrives with a jarring sound.

The process of the lightning occurring is due to differences in electrical charges between the clouds with the earth or between other clouds. As the electrical charge in the cloud moves continuously and on a regular basis, during its movement it will interact with other clouds so that the negative charge will congregate on one side (top or bottom), while the positive charge is assembled on the opposite side.

In the event of such a large potential difference between the cloud and the earth, as well as clouds with clouds, there will be a discharging of electricity from cloud to earth or vice versa to achieve the balance of electrical charge (discharge).

In accordance with IEC 61024-1 standards concerning protection against lightning strikes and IEC 1312 on protection against electromagnetic impulses, the general concept of a lightning protection system according to IEC 1024 – 1 and IEC 1312 standards is as follows.

A functional protection system consists of 2 parts:

  1. External Protection System
  2. Internal Protection System

Integration Ring Grounding with Bare Copper (BC) 50 mm2

External Protection System

External protection systems are tools installed on the outside of the building which serve to protect buildings and people against direct lightning strikes.

3 parts of an External Protection System:

  1. Finial (air terminal/copper tapered rod) mounted at the top of the building which serves to catch the lightning strike directly.
  2. Down Conductor (minimal conductor cable BC 50 mm2) mounted on the outer wall of the building which serves to distribute the flow of electrical charges from the finial to grounding.
  3. Grounding of copper installed in the ground serves to discharge an electrical charge from the conductor cable to the copper rod embedded in the ground. All grounding should be connected directly, or Spark Gap can be used. The smaller the grounding value is, the more quickly the discharge of electric charge from lightning to the ground will be absorbed into the ground (maximum grounding value = 1 Ohm)

Bounding Grounding

Internal Protection System

Internal protection system is a device installed on the inside of a building which serves to protect electrical equipment (electronics) against lightning induction (a momentary but large spike in voltage)

Internal protection system consists of 2 parts, namely:

  1. Equipotential Bonding (EB) is the connecting of all metal/grounding cables to the internal copper plate (PEB = Potential Equalizing Bar), which is to be connected to the main grounding outside the building. This is useful for removing the potential difference in the equipment when they are exposed to lightning induction.
  2. Installation of Arrester in Main Distribution Panel (MDP) with Arrester type Over Current, Sub Distribution Panel (SDP) with Arrester type Over Voltage and in equipment with Arrester type Fine Protector

Lightning protection zone concept

The lightning protection zone concept described in international standard IEC 62305-4 has proved to be practical and efficient. This concept is based on the principle of gradually reducing surges to a safe level before they reach the terminal device and cause damage. In order to achieve this situation, a building’s entire energy network is split into lightning protection zones (LPZ = Lightning Protection Zone). Installed at each transition from one zone to another is a surge arrestor for equipotential bonding. These arrestors correspond to the requirement class in question.

Lightning protection zones concept according to IEC 62305-4 (EN 62305-4)

Lightning protection zones concept according to IEC 62305-4 (EN 62305-4)

  • LPZ 0A: direct lightning strikes & high electromagnetic fields occur
  • LPZ 0B: no direct strike but high electromagnetic field
  • LPZ 1: without direct strike, the electromagnetic field is weak
  • LPZ 2: areas with weak electromagnetic fields
  • LPZ 3: protection area inside equipment

Any electrical, telecommunication, data, and other equipment undergoing a zoning change should be equipped with an arrester. 

Lightning protection zones and comprehensive protection measures

Surge protection devices are classified into lightning current arresters, surge arresters and combined arresters according to the requirements of their installation. Lightning current and combined arresters which are in LPZ 0A to 1/LPZ 0A to 2 fulfill the most stringent requirements in terms of discharge capacity. These arresters must be capable of discharging partial lightning currents of 10/350 μs wave form several times without destruction, thus preventing injection of destructive partial lightning currents into the electrical installation of a building.

Surge arresters are installed at the transition from LPZ 0 to 1 and downstream of LPZ 1 to 2 and higher. Their function is to mitigate the residual currents of the upstream protection stages and those generated in the installation.

Choosing the right surge protection devices

The classification of surge protection devices into types can be matched to different requirements with regard to location, protection level and current-carrying capacity. The table provides an overview of the zone transitions

Arrester type over current (level 1) is an arrester that serves to cut a very large lightning current (maximum 100 kA) and quickly (100 ns) directs its flow to grounding, but there is still a return voltage generated.

Installations of level 1 arresters are typically on the outer side of the power grid (before the meter PLN/parent panel or Genset)

Arrester type over current (level 2) is arrester that serves to cut over voltage (20 kA) from lightning induction and reverse voltage and even more quickly (20 ns) drain it by grounding, Metal Oxide Varistor (MOV) has the ability to cut the lightning voltage inversely with its sensitivity level.

Arrester type Fine Protector (level 3) is an arrester that serves to cut the remaining voltage from the 2nd level arrester (3 kA) and directs its flow to ground within 25 ns.
