GE P144 Numerical Relays

Part of the MiCOM P40 platform, the Agile P14x feeder management relays provide 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 P14x relay family is user-friendly and highly flexible, allowing application on any electrical network.

The MiCOM Agile P14x is an advanced feeder management relay platform with overcurrent and earth fault protection, as well as autoreclose and a full suite of protection, control and monitoring functions. The relay can also be used as high impedance busbar with full scheme supervision. The platform also provides main or back-up protection for MV/HV, solidly earthed, impedance earthed, Petersen coil earthed and isolated neutral systems.

GE P144 Numerical Relays’s 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 – removes 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
