The PCA2 is a complete substation protection performance evaluation and recording system. It tests a number of elements of the protection system. Its advanced software-controlled current source can inject a precise current into the relay whilst the system is on-load. The critical ‘first-trip’ of the relay and circuit breaker can then be captured and automatically analyzed.
The PCA2 also records the tripping supply and trip-coil current profile and additional voltages/contacts/currents as desired. The unit automatically analyses this information to extract data on many aspects of breaker and overall protection system condition. As well as performing a complete system test, the PCA2 can be used for testing over-current relays and circuit breakers individually. It can also be used for analytical studies on many other protection systems, both on and off-load. The PCA2 is a key tool that enables a truly cost-effective Reliability Centred Maintenance Program (RCM) for substation protection.
