Description

GE MiCOM P145 Relay

The GE MiCOM P145 relay provides an integrated solution for the complete protection, control, and monitoring of overhead lines and underground cables, covering all distribution and transmission voltage levels. Providing all essential information to efficiently maintain complex power systems and their components, the P145 relay family is user-friendly and highly flexible, allowing application on any electrical network.

The MiCOM P145 relays are an advanced feeder management relay platform with overcurrent and earth fault protection, as well as auto reclose and a full suite of protection, control, and monitoring functions. The relay can also be used as a high impedance busbar with full scheme supervision. The platform also provides main or backup protection for MV/HV, solidly earthed, impedance earthed, Petersen coil earthed and isolated neutral systems.

Key benefits:

• Full feeder management with efficient monitoring, control, recording, and digital communications
• Supports all major digital control system protocols, easing integration into DCS, SCADA, and engineering workstations
• Fast simple and reliable busbar protection as an alternative application: Numerical single-box solution with full scheme supervision
• Harsh environment protection extends the life of the product
• No internal batteries in GE-branded models – remove a maintenance item and eases air-freight logistics
• 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.
• NERC CIP cybersecurity including role-based access control (RBAC), RADIUS and SysLog

A comprehensive library of hardware options, protection, and control functions suitable to meet your system requirements. Advanced auto recloses and synchronizing options, including predictive closing such that CB primary contacts touch near to the exact moment that systems drift in phase. The standard and user-programmable curves, supplemented by load blinders and voltage supervision offer fast and dependable fault tripping, without constraining circuit loadability. Distance to fault location assists in dispatching of maintenance crews.
