Abstract

Recently, several developments of real-time simulators have been reported. But they are very high cost. And then they are difficult to apply for relay testing in small business. This paper presents the structure and performance of a new pc based, low cost, tester to digital protection relays. Fault transients are generated either by simulating signals using EMTP or by recorded fault signals.
