Motor Insulation Protection Relay

Motors up to 15kV

The MIP-6 monitors the level of deterioration in the insulation of Medium Voltage Motors and is kitted with a resistor box. It measures the motor’s insulation resistance and displays the actual and average highs and lows over a predefined period of time.


The MIP-6 Protection Features: 

  • RTD / Thermistor with two levels for each input 
  • Thermistor PTC / NTC selection 
  • Over temperature Alarm and Trip to each input 
  • Continuous analog output signal 
  • External fault 1 and 2

Protection Inputs can be assigned to any of the following items:   

  • Alarm only - Relay A 
  • Trip only - Relay B 
  • Fan (Trip, Alarm)- Relay C
  • Trip/Alarm- Relay D
  • Enabling Auto Reset 
  • Monitors insulation deterioration of Medium Voltage motors
  • Displays the present and average insulation resistance on LCD
  • Monitoring while motors are de-energized
