Distance Protection P447 1 & 3 Pole tripping/reclosing
Description
P44 MiCOMho 5th Generation
Line Distance Protection
The P44, part of the MiCOM P40 Agile 5th Generation family, is a line distance Protection that delivers high performance processing and a graphical HMI as standard and provides up to 9 zones of subcycle distance protection with both mho/quad characteristics and delta directional comparison (incremental) protection.
In addition, distance phase preference tripping logic and transient earth fault detection (TEFD) for Petersen coil earthed and isolated systems. The P44 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.
Key Benefits:
- Integrated full colour display, for single-line diagram control of the protected bay.
- 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 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
