Three Phase Secondary Injection Kit
Secondary injection tests are performed to verify the correct operation of the protection system with regard to everything that is connected to the secondary of the transformers. The secondary protection system may include Protective Relays, auxiliary relays, protection circuits, communications and control systems, metering devices, low-voltage devices, alarms, etc. Accordingly, the secondary injection test covers not only the testing of protective relays and their tripping settings, but also the checking of all associated circuits and devices involved in the proper performance of the secondary protection system.
