|Key feature||Dual algorithm distance operation|
Part of the MiCOM P40 platform, the Agile P441, GE MiCOM Agile P442 and P444 numerical relay full scheme distance relays provide flexible, fast and reliable protection of transmission and sub-transmission lines. They include full scheme 6-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.
These distance protection systems are ideal for single circuit breaker application, single and/or 3-pole tripping, and includes a full suite of monitoring, control and recording capabilities plus fault locator, autoreclose and check synchronism.
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.

P40 Agile Feeder Management
The P14N non-directional feeder, P14D directional feeder and P94V voltage and frequency IEDs bring the design rigor and technology of transmission applications to the entire utility and industrial market. The footprints of both the device physical size and the lifecycle environmental impact have been minimized using state-of-the-art design, component, and process selection. Agile solutions from GE are ideal for new-build and retrofit alike.
Agility and Versatility
MiCOM P40 Agile IEDs provide an integrated solution for the complete protection, control and monitoring of electrical power systems. Application for overhead lines, underground cables, busbars, breakers, transformers, reactors and distributed generation is supported, right from distribution (as primary protection) to transmission voltage levels (as back-up). The IEDs are suitable for a wide variety of applications in solidly-earthed, resistance-earthed and Petersen coil systems.
