XMR-P

Motor protection, Feeder protection, Generator protection

XMR-P is a part of XMORE platform, the complete range of IEDs for Medium Voltage application including feeder, motor, generator, transformer and capacitor bank; it is the multifunction and comprehensive Feeder, Transformer, Motor and Generator protection which includes an accurate and complete measurement, including Energy and Power.

Thanks to Hardware and Software modularity XMR-P is flexible and scalable in term of application and performance as:

  • Feeder Protection (Standard SW configuration)
  • Feeder Protection with additional Power protection element (SW PAC Power)
  • Feeder Protection with additional Directional Overcurrent and Earth Fault element (SW PAC Directional)
  • Generator and Motor Protection relay (SW PAC Motor)



ACCURATE MEASUREMENTS

Enhancements to protect and analyze power system operation in disturbance conditions:

  • Up to 8 analogue inputs
  • Non conventional CT’s/VT’s inputs
  • 32 sample for cycle Oscillography fault recording
  • 64 sample for cycle measurement for accuracy of protection element
  • Up to 0,5 class Power and Energy measurement
TIME SYNCRONIZATION

Enhanced Time synchronization solution for SOE recording:

  • Precision Time Protocol PTP according to IEC1588
  • SNTP
COMMUNICATION SECURITY

Communication Security through redundancy protocol and Cyber Security package :

  • High available Seamless Redundancy support HSR
  • Parallel Redundancy Protocol support PRP
  • Rapid Spanning Tree Protocol RSTP
  • Advanced built in Cyber Security
NETWORK CONNECTIVITY

Widely implemented in Smart Grid and Substation Automation System:

  • IEC61850 Ed.1/Ed.2
  • IEC 870-5-103
  • Modbus (Serial/TCP)
  • DNP3 (Serial/TCP)
