Description

GE MiCOM P542 Relay

The P54, part of the MiCOM P40 Agile 5th Generation family, is a line differential and distance Protection that delivers high performance processing and a graphical HMI as standard. A cost-effective range of transmission/sub-transmission class protection relays providing comprehensive line differential protection for up-to 3 line ends, with in-built subcycle transmission class distance and directional earth fault protection. This range of products is ideal for HV, EHV and UHV applications on lines and cables for 1 or 2 breaker applications with patented adaptive auto-reclose functionality.

GE MiCOM P542 Relay Key features:

• Integrated full colour display, for single-line diagram control of the protected bay.
• Current transformer supervision operates with or without voltage inputs, to prevent any spurious tripping and raise the alarm
• True subcycle distance protection with up to 9 fully directional distance zones for transmission class security and dependability
• Load blinder prevents spurious trips cascading through the network in extreme conditions such as on the verge of a blackout
• Distance phase preference tripping logic and transient earth fault detection (TEFD) for Petersen coil earthed and isolated systems
• Unparalleled speed, security and selectivity
• With fast start up time of less than 10s, resulting in protection, control and communications without the need to wait
• Full compatibility of the Line Differential communications with all legacy MiCOM P540
• Compatible with 56/64kbps or 2Mbps for direct fiber or MUX communications channels
• Suitable for use with equal or unequal transmit and receive path delays (eg SDH/SONET)
• Suitable for MPLS differential channels
• Full suite of monitoring, control and recording capabilities plus fault locator.
• Multi-shot autoreclosure with check synchronism – adaptive technology to detect fault arc extinction and accelerate the dead time or drive to lockout for persistent faults
• Harsh environment coating as standard for all GE’s MiCOM P40 relays protects against corrosive gases such as H2S or SO2
• No internal batteries in GE-branded models – removes a maintenance item and eases air-freight logistics
• CyberSentryTM  Advanced Security including AAA, Radius, RBAC, and Syslog
• IEC 61850 9-2LE Process Bus capability with PRP in all models
• Secure Data vault with 5000 events, 100 Fault records and over 1000s of Oscillography
• Binary inputs ESI48-4 EB2 compliant
