Ensuring Reliable Switchgear Performance with Circuit Breaker Testing

Circuit Breaker Testing

Circuit Breaker Testing (also known as ‘Trip Profiling’) is essential for ensuring the safety and reliability of the circuit breaker, a key link in the power asset chain. This testing is crucial for maintaining electrical safety and preventing electrical shock.

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

Circuit breakers perform a vital role in protecting expensive equipment from damage through faults. They are designed to protect electrical circuits from damage caused by short circuits and fault conditions. Testing the performance of your circuit breakers regularly is, therefore, an essential and cost-effective part of any maintenance strategy, ensuring both circuit protection and electrical safety.

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

By analysing the current consumed by the trip coil during the circuit breaker’s operation, it is possible to determine whether there are mechanical or electrical issues present. In many cases, such issues can be localised to aid in finding the root cause. Monitoring the tripping supply’s voltage during the operation can detect issues arising with tripping batteries.

Secondary Injection of Overcurrent and Earth Fault Relays

Proper coordination of the protection schemes on a network is essential to minimise the disruption caused by a fault. Secondary injection testing ensures that protection relays operate as intended, safeguarding the electrical circuit.

In addition to these primary tests, dynamic contact resistance tests and primary injection tests can provide further insights into the condition and reliability of circuit breakers. These tests are particularly important in industrial applications where the reliability of the electric power system is paramount. EA Technology also offers testing services for miniature circuit breakers and single pole breakers, ensuring comprehensive coverage of all types of protection devices.
