Phoenix Contact – Your Partner in Safety and Reliability for Railway Industry

From |

RailwayPhoenix Contact has been serving the railway industry for decades, especially for rolling stock and signalling. Safety and reliability has always been our number one concern when developing products for railway applications.

Safety on Board

The basic requirement for safety and reliability is standard compliance. Phoenix Contact has been certified by the International Railway Industry Standard (IRIS) since April 2008 and this standard is based on the quality management standard DIN EN ISO 9001, which has been extended with international railway-specific requirements. The ongoing tests during the development and production cycle of the products are essential to guarantee the product quality.

On top of that, all rail-specific products from Phoenix Contact fulfill the standards of DIN EN 50155, an international standard covering rolling stock; DIN EN 50121 electromagnetic compatibility; and EN 45545, fire protection on rail vehicle. Besides, shock and vibration test, material test and other fire protection is also critical for the railway application.

Safety should not be limited to the big ticket items and should even be extended to the passive component level. For example, the cable markings like shrink sleeve should be halogen-free and fulfill DIN 5510-2 with an oxygen index of 34.9%. besides being halogen-free, the cable ducts should enable individual bars to be broken without using any tools or resulting in any burr through defined breaking points according to EN 45545-2 (R22/R23:HL3). Behaviour in fire is another key concern and the plastic used for Phoenix Contact’s terminal blocks is halogen-free polyamide PA 6.6; which meets the highest safety requirement of UL 94 V0.

Network on Board

Nowadays, commuters demand for “Internet on board” has made the information and infotainment systems essential in trains. The M12 network connectors with a mechanically robust design, in compliance with IEC 61076-2-101, together with high quality cables meeting the requirement of EN 45545-2 will ensure reliable communications. The heavy-duty connector, compliant with IEC 61373, with modular contact inserts form a flexible and safe transmission of signal and power circuit on rolling stock carriage connection and simultaneously ensures comprehensive protection in the event of electromagnetic interference fields.

Surge Protection

Surge voltages and lightning strikes are common issues in signalling, hence the surge protective device (SPD) become significantly important to maintain reliable signal transmission. Phoenix Contact’s SPD has been tested according to IEC 61643-21 and the plug can be disconnected for test and maintenance by using the portable test laboratory. According to IEC 62305-3, the SPD must be tested regularly and the test values should be documented and traceable. Additional features like multi-stage monitoring (green – operating, red – fail and yellow – reach performance limit) for predictive maintenance and remote signalling for early detection of overloaded SPD can help to further enhance reliability.

Power Supply

The power supply unit (PSU) is used to convert main AC to low-voltage regulated DC power and it should at least be compliant with EMC Directive 2014/30/EU, IEC 60950-1, DIN EN 61558-2-16 and UL 508. To ensure smooth operation and maximum uptime, the redundancy setup of the power supply cannot be overlooked.

A redundant system can made up of two power supplies and a diode or Phoenix Contact’s O-RING to prevent back flow of current. An ORING being a more advanced and modern redundancy module compared to the diode, comes with auto-current balancing (ACB) technology which ensures the power supplies work equally hard. This enables the power supplies to have a longer and more consistent lifespan.

The redundancy status as well as the status of the ORING can be monitored, whereas this cannot be done with a DIODE. The PSU becomes more reliable and dependable when it is capable of sending analogue signals to control system on measurement values such as real time current, voltage and power for early detection of operational fault as well as critical information to the user.

Make-before-break – Terminal Blocks for CT Test

From |

Make-Before-Break

Make-Before-Break (MBB) is a term “Denoting a switch or other device in which a new electrical connection is made before the existing one is broken”. In short, it simply means, shorting the circuit before disconnecting it.

You may know about MBB when purchasing a relay. But do you know there are terminal blocks designed with MBB in mind too? These MBB terminal blocks can usually be found in power industry applications.

For those who are familiar, you may have come across this term (MBB) during a Current Transformer (CT) testing on a protection relay. However, do you know the importance of ensuring MBB when conducting a CT test with your Terminal? Or what the consequences will be of not having a terminal blocks that comes with a MBB feature during the test?

Protection Relay

A CT will certainly be at risk of being destroyed or even worse (Explosion!) if the secondary is left open circuit while the primary current is present. This is due to the insulation failing from the “higher than rated” voltage that occurs. Therefore it is extremely important to ensure MBB before conducting a live testing. A good terminal block with MBB feature will definitely help you provide the extra mile in ensuring safety.

How does the MBB terminal blocks function and what does it look like?  Here are some good examples of a good MBB terminal block.

  1. A good MBB terminal block must have the feature where shorting is always present first before you are able to break the circuit. It would be best if the terminal blocks are able to automatically perform the short circuit for you whenever it is being disconnected during the CT test.
    Short Circuit function closed Short circuit function open
  2. Clear indication of Short Circuit and disconnection must be visible and this allows your engineers to have an ease of mind during testing.
    PTME
  3. Good MBB terminal blocks should have safe and easy to operate features. Having said that, these features can help to cut short the time while testing (shorten the risk) and ensuring the safety of the person that is conducting the CT test.

Shunt Reactor Controller

From |

Shunt reactor controller

Shunt reactor

What is a shunt reactor controller? I recall having the same question running through my head when a customer told us about what he was trying to do. Well, before knowing what a shunt reactor controller does, let us look at what exactly is a shunt reactor?

Some of you might wonder “Why does it look like a transformer?”. Yes, you are right, to a certain extent, because a shunt reactor does have similarities with a transformer in terms of its construction. However, they are both very different in terms of their functionality.

While a transformer is used to efficiently transfer power from one voltage system to another to cater for the application required, a shunt reactor absorbs reactive power generated from the source i.e. motors, generators etc.

Active and Reactive Power

What is reactive power and why do we bother to absorb? That might be the next question to ask. Before going into that, we need to understand that in an AC circuit, there are both active power (or real power) as well as reactive power, in which the active power is used to power up a system. To understand this from another perspective, think of it as a pint of beer where the beer is your active power and the reactive power is the foam.

The Beer Analogy of Active and Reactive Power

Reactive Power Analogy with Beer

Image from Electronics Tutorials (http://www.electronics-tutorials.ws)

Let’s put water piping system as an analogy to electric circuit, and voltage is the ‘water pressure’. A certain level of water pressure is required in order for the water to travel across the piping system to the designated location to perform certain task, such as flushing your toilet bowl. Similarly, voltage plays the same role in an electric circuit to ensure that active power can be supplied to run any equipment or device. In this case, reactive power is the key element to maintain the voltage level in a circuitry.

The Water Analogy of Electricity

Water Analagy of Electricity

Hence, instead of using the word ‘absorbing reactive power’, shunt reactor is rather used to stabilize or compensate the level of reactive power in an electric system.

From Component to Solution

Rewinding back a little on how this shunt reactor controller came about. It started with a normal enquiry sent in, asking for a voltage transducer. We followed up with a visit to the customer to understand further.

He showed us the solution that he was going to implement for his end user who runs a palm oil refinery. This was an existing solution in another plant where it was used to control the output of power that being transferred back to the grid from the bio-gas generation using the effluent of palm oil.

  • During the day, when most of the equipment in the plant is running, the whole electric system is highly loaded and more reactive power is consumed. Thus the causing the voltage to drop.
  • However, whenever there is less equipment running, less reactive power is consumed and hence the voltage increase.
  • This is the time when a shunt reactor has to be switched on to compensate the reactive power in order to maintain the voltage level at a particular rating.
  • Each shunt reactor has a fixed rating. Hence, putting several shunt reactors together and adding controls to it can achieve different reactive power compensation at one time, depending on the system load.
  • This whole solution is the basic working concept behind a variable shunt reactor, however cost is always a concern when it comes to such solution.

His idea was to duplicate the same solution in his project. Looking at the pictures he showed us, we believed that it was possible to be implemented with the range of products that Phoenix Contact has to offer. Hence we came up with the solution concept diagram with a brief program flow.

Customized solution from Phoenix Contact

We finally secured the project after a few rounds of discussion and modification to suit best to his application. The list of products that are put into this solution includes:

  1. ILC 171 controller – The processing unit to control the shunt reactor via relay and contactor.
  2. MCR voltage transducer – The main component to take in voltage from the system and convert it to readable value for the controller.
  3. UNO power supply – Main power source to the controller and other peripherals.
  4. TP 3150 Touch Panel – Serve as a HMI for the user to control the shunt reactor controller and display of current value of the system.

Let there be light: Phoenix Contact Components for Reliable Power Grids

On 7 July 2017, Phoenix Contact Singapore Team organised a’ Dining in the Dark’ event as part of Corporate Social Responsibility.  In the short 2 hours without our sight, we experienced a range of emotions such as fear and helplessness. This event also allowed us to understand the challenges that persons with visual impairment faced daily. It is truly a meaningful event that we are thankful to be able to experience with the friends we made from work.

Phoenix Contact's 'Dining in the Dark' CSR Event

Phoenix Contact’s ‘Dining in the Dark’ CSR Event

In today’s world, it might not be an exaggeration to say that we will feel the fear and helplessness if we do not have access to electricity. For a start, life-sustaining equipment in hospitals will not be in operation. Many of life’s conveniences such as lights, entertainment, air-conditioning etc. will be stripped from us. For this, electrical grids are always considered critical infrastructure all around the world and efforts are made to ensure the grid is always operating. Phoenix Contact contributes to this reliability with our products. Below are some examples:

  1. Terminal blocks (Clipline Complete)Clipline terminal blocks

CLIPSAFE – Your one-stop junction box solution

From |

The “Blame Game”

Have you ever been bothered by such a situation?  Picture this, you have just completed your run on a beautiful day only to return home and realize that your feet are full of blisters. Should you put the blame on the shoe manufacture for using a material that is too tough, or would you blame the socks company for using a material that is too soft?

Things can potentially get uglier when it comes to planning for or executing a project. Have you had the unfortunate experience of opening a ‘Brand X’ junction box, to find yourself having ‘Brand A’ terminal blocks and maybe some ‘Brand C’ cable glands or markings inside. If there is a fault, who you should go to?

You may potentially find yourself being trapped in the “Blame Game” if you are having two or more different suppliers involved.  And if you have ever been trapped in one, you will know that the chances of successfully finding a solution and getting out is very minuscule.

What if there was a supplier who could provide you with a one-stop shopping experience?

Building installation with push-in three-level terminal blocks

From |

Thanks to the new PTI 4 three-level installation terminal blocks with push-in connection technology from Phoenix Contact, rigid conductors up to 6 mm² can be easily and directly wired without tools. The terminal blocks are specially tailored to the requirements of the electrical installation and the distributor construction, thanks to their compact design.

freistellen mit Pfad CD-Inlay einbauen Network Interfaces fg

The snap-in, no-screw disconnect slide with status indicator makes contacting the neutral busbar easy and safe. The function shaft on each level provides for easy potential distribution, thanks to the flexible jumper system. Each terminal point can be clearly marked and, in addition to the testing facility, has its own test connection in the function shaft.

Thanks to the insertion force, which has been reduced by 50 percent, it is possible to insert solid and stranded conductors with ferrules and cross sections from 0.5 to 6 mm² without tools. The built-in actuation lever allows fully insulated release with any tool. The orange-colored button indicates the actuating element. This prevents the terminal from being activated accidentally. Flexible conductors without ferrules can also be connected, from 0.2 mm by actuating the lever.

The push-in three-level terminal blocks share all the system characteristics with the CLIPLINE complete terminal block series and are therefore compatible with all installation terminal blocks from Phoenix Contact.
