Circuit Breaker Testing

Circuit Breaker Testing is used to test both the performance of individual switching mechanisms and the timing of the overall tripping system. Circuit Breaker Testing is essential to ensure the safe and reliable performance of this key link in the power asset chain.

• Quick and easy to perform on site
• Circuits can be tested on or off load
• Tests performance of whole tripping cycle
• Tests overall timing of tripping system
• Identifies need for lubrication of maintenance

Circuit breakers perform a vital role in protecting expensive equipment from damage through power surges and faults. Testing the performance of your circuit breakers regularly is therefore an essential and cost-effective strategy.

EA Technology’s Circuit Breaker Testing service consists of two tests to assess the condition and performance of the tripping system:

Circuit Breaker Trip Test

To test the performance of the various elements of the tripping cycle to identify and eliminate potential performance problems.

Secondary Injection of Overcurrent Relays

To test overall protection timing to provide a report on protection performance at specified relay settings.

Circuit Breaker Testing is an essential part of any condition based asset management programme.
