Using a real time digital simulator to simulate multiple CT's for testing relays in current differential protection systems

The comprehensive testing of protection relays in differential current schemes involving multiple current transformers has in the past required access to a high current test plant and could be highly time consuming.

Zusammenfassung:	The comprehensive testing of protection relays in differential current schemes involving multiple current transformers has in the past required access to a high current test plant and could be highly time consuming. This paper describes how a real time digital power system simulator is now used for these tests and the increase in testing efficiency thereby achieved.
