P50 Agile P15D Feeder Protection

Product Price : Get Latest Price

The Agile P15D is a dual-powered non-directional overcurrent and earth fault relay. It provides protection for applications where no external auxiliary power is available or the auxiliary supply does not guarantee the dependability required for protection applications. The relay is designed for MV/LV industrial installations, distribution network substations and more specifically in RMU networks for protection and monitoring purposes. It may also be applied for direct refurbishment of substations using older induction-disc IDMT overcurrent relays, as the P15D energizes from the line current transformers in the same way that the disc relay derived its operating power source from the CTs only.

The main protection functions are timed and instantaneous phase and earth fault protection, with up to 3 independent stages available. Thermal overload, cold load pickup, inrush blocking and multiple setting groups add to the application capabilities of this versatile relay.

Key Benefits:

  • CT only or dual-powered relay
  • Minimal burden on substation battery when the feeder is energized
  • Cost effective, compact size
  • Measurement, protection and monitoring in one box
  • Front USB port for local communication
  • Internal battery maintains the LCD and communication during faults Substation staff can power-up the relay for interrogation even when the feeder is de-energized

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.

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: Numerical single-box solution with full scheme supervision
Harsh environment protection extends the life of the product
New advanced opto 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.
