Cable Entry System – CES

From |

Have you ever left your earphones in your pocket and when you wanted to use them again, they emerge as a tangled ball of mess? Annoying, isn’t it?

Well, the wiring of current and conventional electrical panels brings about a similar problem. The above picture shows its set up and at a glance, three words pop up in my mind: Complex; Costly; Time-consuming.

So why is this so?

Firstly, in the current system, multiple holes of different sizes need to be drilled in accordance with the cable sizes. Imagine the hassle having to drill ten holes of different diameter just to see messy wires intertwined together.

Next, a common occurrence to such wiring systems is the need to add additional cables. If you are lucky, there will be enough space on the flange plate to drill the extra holes. However, if the space is insufficient, or if you need larger holes for new cables, you would most likely have to replace the entire electrical panel and redo the entire wiring system from scratch. Not only does this add on to the hassle, it also adds on to labour and cost.

Lastly, conventional wiring systems require more time to rectify problems in communication. This is due to the difficulty in identifying specific cables especially when they are bundled together. The troubleshooting process thus leads to longer downtime which means financial losses for the company.

The Solution

Phoenix Contact has thus come up with a solution to eliminate this problem. Our Cable Entry System (CES) comes with specific features to tackle the hassle of the conventional system.

Firstly, only one or two holes would have to be cut to enable installation of up to ten cables in the system, greatly reducing the set up time. Furthermore, the CES can cater to different cable diameters ranging from 2mm-24mm. All these can be easily installed by mounting the sleeves of varying sizes on to the robust metal reinforced frame.

Next, additional cables can be installed by removing the blind sleeves from the extra cable holes provided by the CES. In the event that the existing cable configuration has to be amended, the CES allows for easy reassembly just by replacing the sleeves with those of different cable diameters. This eliminates the trouble of cutting out new holes on the flange plate.

Lastly, the CES allows cables to be easily identified as the rectangular frame organizes the sleeves holding the cables in an orderly manner that is easy on the eyes.

Besides tackling the inconveniences of the conventional electrical panel wiring, the CES offers protection class of IP54, making it suitable for harsh environment conditions.

If your current electrical wiring system reminds you of your ball of tangled earphones, it‘s about time you switch to Phoenix Contact’s Cable Entry System. Our CES will be the solution to increasing your productivity and cost saving to your electrical panels wiring.

System Cabling Solution for Process Industry

From |

One of the challenges which panel builders in the process industry face would be space saving on control cabinets. Many Process retrofitting jobs require panel builders to ensure the quantity of cabinets remain even though additional I/O’s are added. System cabling is one of the best solutions to save space in control cabinets.  One of our panel builders solved their problems by replacing terminal blocks with our VARIOFACE Interface Module for the project.

Problems:

  • Additional 150 I/O’s on current system
  • Additional Controller Module
  • Cabinet Quantities need to be remained

After going through the product technical information, panel builder engineers decided to replace most of the signals with our VIP Interface Module due to space constraints. There are a total of 115 units of VIP-3/SC/D37SUB/F installed in this project. Photos of the panel are shown below.

Control Cabinet

Features of Interface Module:

  • Compact design of control cabinet space
  • I/O marking for field wiring clearly identified
  • Flexible marking of modules
  • Metal mounting foot allows for easy installation and removal on din-rail
  • Allows flexible module mounting positions

In addition to the space saving advantage, the site engineer shared that it is also time saving and fault free during the wiring termination. When the panels are delivered, the end user saves valuable time when installing and troubleshooting

LV Compartment for MV Switchgear

Box by box towards Smart Grid 1: LV Compartment for MV Switchgear

The gradual shift towards the much vaunted Smart Grid structure has been gathering steam in the last few years. While much of the excitement has been generated from the immense potential of what a fully completed Smart Grid system can bring (for example, higher reliability at reduced cost), Grid operators, independent power producers and their team of engineers are facing real difficulties in implementing such systems today. It is easy to talk about wanting to implement technologically advanced systems, but when it comes to actually executing the projects to implement such solutions, the complexity surrounding such implementations comes to the fore.

Much of this complexity arises because of the vast variety of applications within the industry. It is particularly difficult to find the right set of products that are suitable for the application, reliable, fast to set up and easy to manage. For example in Transmission and Distribution substations, there will minimally be systems for transformers, shunt reactors, switchboards, intrusion detection monitoring systems and each of these systems can consist of smaller sub systems. For example, in monitoring a switchboard, we can monitor downstream load current for energy balancing; micro current fluctuations for signs of partial discharge or even for predictive maintenance; door contact monitoring for physical security and the list goes on. Each of these systems will require the right set of products and will have to be linked in this web of madness. Imagine the chaos!

At Phoenix Contact, we recognise this difficulty. While we have many solutions for Energy Industry that we are always sharing with the various stakeholders, in this series of blog articles, we will be examining how we help to simplify the implementation of Smart Grid. We will do so by examining the building blocks of a system – the individual panels which form up a system; and we will do so box by box. This first article will be about LV Compartment of MV Switchgear and we will delve straight into the 3 problems switchgear builders and grid operators are facing!

Problem 1: How do I collect signals from my switchgears and transform it into IEC61850?

The completed substation topology will involve decentralised controls where IEDs are placed at high voltage equipment (on transformers and switchgears) itself. Even when it is not completed, communications from the bay control cabinets and protection devices to the substation control system are being converted to IEC61850 as IEC61850 has proved to be a superior communication protocol and standard to reduce downtime and increase reliability of the grid. Therefore, it is only a matter of time before all switchgears are converting signals from the circuit breakers and all other auxiliary signals into IEC61850 data. However, examining the LV compartment of switchgears today, the signals are still being passed out with many copper wires or connected to numerical relays. These present two clear drawbacks:

  1. There are a lot of copper wires going out of the panel or into numerical relays. The associated cost includes requiring marshalling or pilot cabinets and related components and regular maintenance to check if the connections are good. In addition, it is difficult to isolate where the fault is when there is a loss of signal. In the worst case scenario, there might even be accidental shorting resulting in severe downtime!
  2. Numerical relay and its I/O cards are expensive.

These result in higher initial cost and higher eventual maintenance cost with downtime not necessarily minimized, especially in the event of loss of signal.

Using of a Bus coupler capable of communicating via GOOSE and MMS will solve both of these problems. Using Phoenix Contact bus coupler as an example, the signals can be easily inserted and aggregated as IEC61850 data. It certainly reduces the number of cables leaving the cabinet and with the light indicators, you can see clearly which connections are good without requiring extra tests. It is also of lower cost compared to numerical relays’ IOs while communicating perfectly with them.

Problem 2: There are too many wires, how can we manage them better?

Being the founder of the original ceramic terminal block, it is already tempting to say that Phoenix Contact is the best at solving this! But in the last few years, we have developed more data connectors to put us in a better position to solve this for switchgear builders!

We have an extremely wide range of terminal blocks for every applications and needs. We have demonstrated to be able to meet each and every customers’ unique demands, be it requiring pluggable solutions, fastest connection technology, space saving, you name it, we’ve done it!

In this article, we would just like to highlight how a commonly used connector for switchgears has developed to adapt to Smart Grid. In the past, our Heavycon (heavy duty connector) was often sold to connect the LCC and Bay cabinets. This enabled quick connection on site.

 

However, these connectors are usually for loose copper wires only. Although you can strip an Ethernet/serial connector to use such connectors, these connectors does not cater very well for the shielding required for data connector. Therefore, Phoenix Contact has developed a modular connector, allowing you to use your data connectors directly! This modular connector even allows you to have connectors which allow for high power!

Problem 3: With more signals being collected, there will be more testing to be done. How can we ensure we are safely doing the testing all the time!

Every so often, testing needs to be done on the current transformers and voltage transformers regularly. For current transformer especially, if not done right, explosions can happen. Currently, the shorting and breaking of circuits are done manually by hand (yes you read that right) and as you can imagine, explosions lead to death.

To solve this, Phoenix Contact has developed our test disconnect system (FAME) where shorting is done automatically and it is fool-proof!

 

Instead of using terminal blocks that are switched manually, you can replace it entirely with FAME and from then on, every testing procedure will be done how it is meant to be done: SAFELY.

We have assembled this product into a demo box along with other products that Phoenix Contact offers for LV Compartment for MV Switchgear. If you will like to have a look at the demo box up close, do contact us using the form below and we will get in touch!

CUTFOX 10 Automated Cutting Device

From |

Are you still using cutters to manually cut wires? Of course it would be practical if the job scale is small, involving less than 480 pieces of wire of length 0.5m daily.

What happens when you have a bigger job, where you are required to cut more than 1000 pieces of wire of length 0.5m every day?

One possible solution would be to buy another cutter to fulfil this requirement.

However, in doing so, you have an increased the labour cost to that of 2 well-trained operators.

Also, this does not account for human errors as well as quality issues. Are humans capable of repeatedly cutting wires of fixed length with an acceptable precision? Are they capable of running non-stop without tiring, constantly producing an output of virtually identical wires for extended periods of time? All of this would lead to increased costs and wasted materials.

With that in mind, what could cut wires with a consistent precision and can operate for long durations on end without rest? The answer is simple – a machine. Introducing Phoenix Contact’s CutFox 10.

Compared to the same range of automatic wire cutting tools in the market, our CutFox 10 has 2 additional functions with regards to its Speed & Software:

  • SPEED – Maximum Throughput of wire is 8mm with 0.5m/s max. feed rate.
  • SOFTWARE – CUTSOFT allows the CUTFOX 10 to read Microsoft Excel files, which can be exported to the machine. You can create a table of data with records of cutting jobs, containing information on the number of wires and length desired. These data records are then processed sequentially by the CUTFOX 10.

The Cutfox 10 not only cuts your labour costs, it also removes the costly element of human error and fatigue. In doing so, quality output is assured. In addition, it is also safe to use, compared to a manual cutter in the hands of a tired and weary operator, minimizing the risk of an accident.

This piece of automation ensures Return of Investment (ROI) in less than 6 months of constant usage, in addition to solving your manpower, quality and safety issues. If you are sick of cutting many, many wires, then this device is perfect for you!

CT Testing with FAME

From |

Test disconnect terminal block might not be an alien term to you, especially if you are in the power industry and dealing with switchgears. This is the most common component you will see in a control relay panel, which allows you to do testing and short circuiting of current transformers. At Phoenix Contact, we incorporate different connection technology into our test disconnect terminal block series, namely the screw connection, spring cage connection and push-in connection. Of course, the changes to our test disconnect product series do not end there.

Figure 1: (From left to right) Screw connection, spring-cage connection and push-in connection

While test disconnect terminal blocks offer flexibility to the user, as well as the benefit of saving space because of its modular design, it still has a slight disadvantage when it comes to testing. During function testing of current transformers and voltage transducers, performing combine switching operations across several points is often a requirement, and thus there will be limitations when it comes to such situations when modular terminal blocks are used. With all the constraints and limitations that comes with using a modular test disconnect terminal block, it opens up greater possibilities for the product development team to explore creative designs to solve the problem while maintaining the benefits of the modular terminal block. With that, ladies and gentlemen, I introduce to you FAMEFast And Modular Energy System, a solution specifically designed to cater to the need for performing complex switching operations, all at once.

Figure 2: FAME Plug and terminal strip

Figure 2: FAME Plug and terminal strip

If you find any of the above foreign to you, no worries! I have got you covered with quality posts by our product specialist. In this post, you will learn the fundamentals behind the make-before-break principle of a CT testing, as well as the reason for using test disconnect terminal blocks in such applications. Next, we look at FAME in detail from its basic operation to the difference between FAME 1, 2 and 3. These few posts will lay down the foundation for your understanding of the field of test disconnect systems.

While FAME is created for CT testing, and several versions of FAME have been developed for the different requirements of relay testing in different countries, we came to realize that there is room for other applications that FAME is able to offer. One specific example that best illustrates this is our recent product approval in Tenaga Nasional Berhad (TNB), Malaysia’s national grid operator. It all started with a product presentation of FAME 1 to the product approval committee members of the Protection Department of Transmission Division, with the purpose of having Phoenix Contact to be specified in as the test plug. However, things started to side track from our original plan when FAME 1 was proposed to be adopted as a secondary safety check in their Control Relay Panel. This is part of the initiative of TNB in the implementation of live maintenance. In this new add-on design, our FAME 1 will be sitting in between the first isolation (terminal block) and the trip coil.

Figure 3: Diagram of group isolation link in protection panel

This secondary isolation, also known as the group isolation link is used to isolate trip contact in a group.

  • It consists of two components, the power plug and the terminal strip.
  • During normal operation, the power plug is inserted into the terminal strip, forming a closed contact between the terminal block and the trip coil
  • When live maintenance is carried out, the power plug will be disconnected from the terminal strip, leaving an open contact.

 

Figure 4: (From left to right) Power Plug and Terminal Strip

This application in Malaysia is a good example and reference of how FAME can be adapted to serve different applications from its original design purpose. If you have a bright idea of how you can use FAME while reading this post, we welcome you to contact us using the form below. Who knows, your idea could be the next new application of our FAME!

Solar String Combiner Box Selection Criteria

From |

“I would like to have a quotation for a solar string combiner box. Please give me the quote ASAP.”

Two of the many possible options

This is the request that we always receive from customers when they want our proposal on solar string combiner boxes (SCB). Unfortunately, we will not be able to offer anything with such a brief statement like this. With that being said, we would like to take this chance to explain to the customers what information is required in order to help us to propose the right SCB for you.

  1. Maximum open-circuit voltage (Voc)
    First, we need to know the maximum open-circuit voltage (Voc) of your solar system design, whether it is 600 / 1000 / 1500V DC. The most common Voc in the market now is 1000V DC and we are also moving towards 1500V DC in Malaysia. This Voc is totally dependent on the system design.
  2. Maximum short-circuit current per string
    So where can we find this info? We are able to know what is our maximum short-circuit current by identifying the short-circuit current of the individual solar module that you have selected, and then multiplying it with the maximum short-circuit current multiplier. Every country has their own specific requirement for the maximum short-circuit multiplier; it can be 1.25 or 1.5 and etc.
  3. Input and Output
    Input here is referring to the number of solar strings going into the SCB and output is referring to the number of MPPT (Maximum Power Point Tracker) involved. You will be able to find the info on the number of MPPT from the inverter that you are using in your system. Once this is confirmed, we will know the configuration you need for your SCB.
  4. Fuse holder Polarity
    We need to also find out from the customer whether they would like to have fuse holder at positive polarity only or at both positive and negative polarity. From protection point of view, we encourage our customers to have fuse holder at both positive and negative polarity because this will give higher protection to the SCB on the incoming side. However, it is still fine to have fuse holder at only positive polarity to fulfil the local standard requirement.
  5. String termination at SCB
    Sunclix Connector

    Sunclix Connector

    Phoenix Contact SCB always comes with Sunclix plug-in connectors instead of normal cable glands. This is because our Sunclix connectors make string cable installations fast and efficient. No additional tools are required to connect our Sunclix connectors. Our SCB are customizable, if the customers are more comfortable with cable glands, we can always revert back to using them.

  6. Monitoring features
    Our SCB is able to monitor both voltage and string current if these are required using our Solarcheck modules, which uses Hall’s effect.

Other than the above, our SCB comes with many other great features that will help you in your solar PV system. If you are interested in our solar string combiner boxes, please feel free to contact us by filling up the form below.

Why Use Safety Relays?

From |

Let’s say you are asked to be a Design Engineer for a day and are tasked to come up with a Process Control Safety System. What are the questions you should ask? 

  • What happens to the Safety Instrumented Systems (SIS) when the relay contact is welded?
  • When did it happen?
  • Where can you find this faulty relay?
  • Why did this happen?
  • Who will be responsible for monitoring this fault?

Safety Relays are devices that implement safety functions. In the event of a hazard, a safety relay must work to reduce risk to an acceptable level. The safety relay must initiate a safe and reliable response as well as monitor the integrity of its function.

The Process Automation Fire & Gas System is always on standby mode and it becomes more important to have multiple diagnostics to make sure the relays used in the Fire and Gas System Safety remain functional with all wiring connected.

7 Functions the ideal safety relay should have for Fire & Gas Systems:

  1. Power loss diagnostics to field devices such as the Beacons, Solenoid Valves and Fire Sounders.
  2. Field devices disconnection diagnostics.
  3. Alerts when Field Devices short circuit.
  4. Welded relay contacts diagnostics.
  5. Able to Proof Test relay points without the use of external power.
  6. Diagnostics via the same cable to the relay coil by the use of test pulse filtering. This also saves money as there is no need for additional DI cards and cables for monitoring function.
  7. Option for redundant connection to the relay coil.

PSR-PC50 Series SIL Coupling Relay

PSR-PC50 Series SIL Coupling Relay

The Phoenix Contact PSR-PC50 series SIL Coupling Relay has the 7 functions you are looking for and it can also be used for power adaptation and electrical isolation in Safe-State-ON applications up to SIL 3 according to IEC 61508 as well as IEC 61511.

This category 3 device is designed for installation in zone 2 potentially explosive areas. By filtering the controller test pulses, premature failure of the safety relays is prevented. The contact side is fully monitored for open circuits and short circuits as well as load and diagnostics supply voltage. If an error occurs, the internal device input impedance is affected. As such, the test pulses sent from the controller are disrupted and the error is reported to the corresponding digital output without additional wiring effort.
