GE MiCOM Agile P441, P442 & P444 Distance Protection Relays

$1.00

The Agile P441, P442 and P444 numerical full scheme distance relays provide flexible, fast and reliable protection of transmission and sub-transmission lines. They include full scheme 5-zone distance, plus aided directional earth fault (DEF) and comprehensive backup protection for utility lines and cables at all voltage levels, particularly oriented towards transmission grids.

Ideal for single circuit breaker application, single and/or 3-pole tripping and include a full suite of monitoring, control and recording capabilities plus fault locator, auto-reclose and check synchro.

  • Dual algorithm distance operation for maximum fault detection dependability
  • Deploy in digital substation architectures with merging units and non-conventional instrument transformers using IEC 61850-9-2 process bus
  • Distance to fault location assists dispatching of maintenance crews
  • Full-scheme relay offers fast, discriminating response to double-circuit, cross-country and evolving faults

Description


The Agile P441, P442 and P444 have a settable quadrilateral operating characteristic that offers consistent 0.85-1.3 cycle zone 1 operating time for general distance application. Customers have a choice of cost-effective built-in teleprotection: InterMiCOM64 at 56/64 kbit/s for direct fiber or MUX links with 2 or 3 ended applications, or EIA (RS) 232 for MODEM links in 2 ended applications. The IEC 61850 redundant Ethernet supports self healing ring, RSTP, dual homing or PRP.

Key benefits:

  • Comprehensive communication options including IEC 61850 and redundant Ethernet ports
  • IEC61850-9-2 interface option allows integration within digital substation process bus architectures
  • Variety of built-in aided schemes over 2 channels
  • Unparalleled speed, security and selectivity
  • Universal IRIG-B – Modulated and demodulated supported in the same model
  • HSR Ring – Extended to 50 node support for larger substation architectures
  • Fast performance, particularly in onerous applications such as where process bus GOOSE is used for tripping purposes

Models:

  • P441 Line-Distance Management IED
  • P442 Line-Distance Management IED
  • P444 Line-Distance Management IED for Transmission
