GE MiCOM P444<\/h1>\n

Part of the MiCOM<\/a> P40 platform, the GE MiCOM P444 numerical relay full scheme distance relays provide flexible, fast, and reliable protection of transmission and sub-transmission lines. Agile P444 Distance Protection System Numerical Relay 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.
\nThese 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.<\/p>\n

P444 Micom AgileKey features:<\/h2>\n

\u2022 Dual algorithm distance operation for maximum fault detection dependability
\n\u2022 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
\n\u2022 Distance to fault location assists dispatching of maintenance crews
\n\u2022 Full-scheme relay offers fast, discriminative response to double-circuit, cross-country, and evolving faults
\n\u2022 No internal batteries in
GE<\/a>-branded models \u2013 removes a maintenance item and eases air-freight logistics
\n\u2022 NERC CIP cybersecurity including role-based access control (RBAC), RADIUS and SysLog
\n\u2022 Alstom P444 provides advanced binary inputs that 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<\/p>\n

The GE MiCOM P444 has a settable quadrilateral operating characteristic that offers consistent 0.85-1.1 cycle zone 1 operating time for general distance application. Customers have a choice of cost-effective built-in teleprotection with InterMiCOM, to implement permissive, blocking, and inter tripping schemes.
\nThe IEC 61850 redundant Ethernet option offers RSTP and IEC 62439 PRP\/HSR \u2013 with the HSR support extending for up to 50 nodes in a station bus ring.<\/p>\n
