Transmission Line Protection Relay Product Overview The L-PRO provides easy to use, state of the art comprehensive distance and backup directional line protection for all voltages including Extra High Voltage transmission lines using communication based schemes. It provides control, automation, metering, monitoring, DFR-quality fault oscillography, dynamic swing recording, fault logging, sequence of event logging with advanced communication features in a flexible, cost effective package. L-PRO can be for High Speed Protection and Complete Control in Multi breaker Applications to all bus types such as ring or breaker-and-ahalf arrangements. The L-PRO takes into effect the influence of adjacent parallel lines through mutual coupling settings. • Easy-to-use, intuitive setting and analysis software • IEC 61850 communication along with Optional PRP (IEC 62439-3) via optical/copper ports • Selectable Single and 3 Pole Trip and reclose • High Speed Five Zone User defined Mho or Quad Characteristics for Phase and Ground Distance Protection • High quality fault recording, swing and event log • Single and Multi Breaker Applications (i.e., Ring Bus and Breaker and Half Configurations including Individual Breaker Failure) • 4 Shot recloser with dead line / dead bus control and Sync. Check • 8 setting groups to accommodate for various o
