Transmission Line Protection Relay Product Overview The L-PRO 4000 provides easy-to-use, state-of-the-art comprehensive distance and directional line protection for medium to extra-high-voltage transmission lines using communication-based schemes. It provides control, automation, metering, monitoring, fault oscillography, dynamic swing recording, fault logging, event logging with advanced communications in a flexible cost effective package. Apply the L-PRO 4000 system for high speed protection and complete control in multi-breaker applications in ring or breaker-and-a-half arrangements. The L-PRO 4000 is ideal for multi-circuit line applications to monitor mutual coupling. • Easy-to-use, intuitive setting and analysis software and individual breaker monitoring) • IEC 61850 communication via optical/copper ports • 4 shot recloser with dead line/dead bus control and • Selectable single and 3 pole trip and reclose sync check • High-speed five-zone user-defined mho or quad phase • High quality fault and swing recording and event log and ground distance protection • 8 setting groups for many operating conditions • Single and multi-breaker applications (i.e. ring bus and • Ethernet ports with 2 unique MAC addresses breaker-and-a-half capability, including breaker failure accommodate network access security needs
