GE MiCOM P442 | Alstom Distance Protection System Numerical Relay

GE MiCOM Agile P442, P441, and P444 numerical relay full scheme distance relays being part of the MiCOM P40 platform,  provide flexible, fast, and reliable protection of transmission and sub-transmission lines. GE MiCOM P442 includes 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 include a full suite of monitoring, control, and recording capabilities plus fault locator, auto reclose, and check synchronism.

Key features Of GE MiCOM P442:

• Dual algorithm distance operation for maximum fault detection dependability
• Deploy in traditional CT/VT applications or 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, discriminative response to double-circuit, cross-country, and evolving faults
• No internal batteries in GE-branded models – removes a maintenance item and eases air-freight logistics
• NERC CIP cybersecurity including role-based access control (RBAC), RADIUS and SysLog
• Advanced binary inputs comply with the harshest norms for surge withstand, plus the ESI 48-4 EB2 standard. Spurious wiring pickup is eliminated without the use of interposing relays, external resistors, or time delays. Battery/wiring faults, switching noise, and induction from long parallel circuits are tolerated without misoperation

P442 Distance Protection system Overview

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 teleportation: 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.

Alstom P442 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
