Abstract

This study identifies the comparison of Technical specification and Characteristics of DC Protection Relay(ETCPU200) used in DC Distribution System in Korea. ETCPU200 has completed Field Test and approved its capability by finding out causes of recent operations through lately developed digital DC protection relay in parallel operation at Maebong-Substation, Nakseongdae-Substation, Euljirosaga-Substation, Jegi-Substation and Chongryangri T/P area. It also examines additional features for efficient System Analysis and Operations.
