Description

GE Micom P44391AB7N0790M | Alstom Agile Transmission Protection relay

Part of the MiCOM P40 platform, the GE Micom P443 numerical full scheme distance relays provide flexible, fast, and reliable protection of transmission and sub-transmission lines. GE Micom P443 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 P443:

• 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 GE Micom P443 relay offers a fast, discriminative response to double-circuit, cross-country, and evolving faults
• No internal batteries in GE-branded models – remove 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
