PHPC01 current booster is an accessory which can work together with protection relay test kit to test transformer protection relay testing. It is specifically designed to supply high compliance voltage even at small current range. It is also suitable for testing high burden electromagnetic current relays.
It works with the Powertest software testing module named High Burden Relay to complete the testing. And only PW460 and PW636i are applicable with high burden relay testing. The power is injected from the PW636i/ PW460 through the current booster interface.
