Megger is your ideal partner to help you to address the rail industry's unique challenges

Protection systems protect people and assets. Are you sure your DC high speed breakers will trip at the right level and fast? Will your protective relays detect the short circuits and overcurrents? If a failure occurs, at best the trains will simply stop. At worst... a nightmare could unfold.

How to test DC High Speed Circuit Breakers

The process of testing a railway operator's electrical network has changed significantly. Some agencies are still hesitant to test, others use old-school methods such as short-circuit testing. Modern test equipment verifies the condition of critical components such as DC circuit breakers and protective relays accurately, quickly and safely. Just connect the test set to the device under test and press the button - It's that simple!

Application note
Testing protection systems in a DC traction substation
Traction power substations deliver energy for trains. AC power is converted to DC and made available to the trains by means of a third rail (metro) or a catenary system (national rail, light-rail, tramway).

Application note
Testing protective relays in a DC traction power substation
The protection system in a traction power substation consists of a circuit breaker, which is most probably a DC high speed circuit breaker, and often a protective relay.

Testing thermal breakers found in marine applications
The BALTO system was originally designed for testing DC high speed circuit breakers. These breakers have a very simple characteristic, they should always trip at the set maximum current (Ids) within a fixed time.
