| Abstract |
Digital protective relay in power system play a prominent part. Simulators for the relay test were introduced in early 1980's. A number of open loop designs have been developed and 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 of low cost and performance of a new pc based tester for digital protective relay testing. The proposed tester was simulated of off-line with fault transient signals obtained from EMTP. |
