MPR-6/3-DGF Motor Protections Relay with Direct Ground Fault

With Directional Ground Fault Function & 3 Thermal Sensors The MPR-6/3 Motor Protection Relay is a new generation of microprocessor based relay designed to protect three phase induction motors. The MPR-6/3 incorporates two main functions. •Motor protection. •Supervision and communication. A comprehensive protection device is required to accurately create a Thermal Model for the motor to run safely up to its limits. This relay should protect the motor from abnormal conditions in the power supply, motor and cable faults as well as operator malfunctions. The MPR-6/3 monitors three phase currents (true RMS line currents are measured at a sampling rate of 0.5 mSec). The MPR-6/3 monitors ground fault current (true RMS) and zero sequence voltage (3Vo), for Directional Ground Fault protection. The MPR-6/3 monitors three temperature (RTD or PTC/NTC Thermistor) inputs. Finally, the MPR-6/3 provides a comprehensive protection package.
