Pcs-931 Line Differential Relay

We are highly proficient in manufacturing, exporting and supplying a huge array of PCS-931 Line Differential Relay from Navi Mumbai Panvel, Maharashtra, India. The PCS-931 relay provides full-scheme current differential and distance protection solutions for transmission lines with high- speed sub-cycle distance element. As well, the pilot scheme of distance protection and earth fault protection are integrated to provide a complete protection solution for the transmission line. The PCS-931 is intended for application on overhead lines and underground cables with diverse voltage levels, including series compensated, double-circuit, heavily loaded, weak infeed (WI), short and long lines. The relay provides dual pilot channels used for redundant tele-communication or three-terminal line application. It can meet the requirements of single-pole or three- pole tripping, it also provides single- and/or three-pole auto- reclosing functions. The PCS-931 is suitable for single- and dual-breaker applications, providing optional dual CT inputs, dual breaker failure protections, dual breaker auto-reclosing and dual synchro-checks. Additionally, the relay provides the remote/ local control of circuit breaker, disconnector and earth switch.
