Functions of SR750-P5-G1-S1-HI-A20-R:
Feeder protection: The main function of this relay is to protect the feeder (cable or line) from various faults and abnormal conditions. These may include:
Overcurrent: Excessive current flows through the feeder.
Over/Under voltage tage: Voltage levels beyond the acceptable range of the feeder.
Ground fault: Leakage current to ground.
Phase imbalance: Unequal currents flowing in the three phases of a three-phase system.
Monitoring: Relays monitor various electrical parameters on the feeder, such as voltage, current, power factor, and frequency.
Control: Depending on the monitored parameters and pre-programmed Settings, the relay can take control measures to protect the feeder. These operations may include tripping circuit breakers, sending alarms, or taking control of other devices.
Metering: Some models in the SR-750 series may offer metering features that provide data on power consumption and other parameters.
Applications:
The SR750-P5-G1-S1-HI-A20-R feeder management relay is used in a variety of applications where electrical feeders need to be protected and monitored:
Distribution systems: Protect feeders in factories, commercial buildings, and utility substations.
Motor control center: Protects the feeders that supply power to the motor.
Renewable energy systems: Protect feeders in solar, wind and other renewable energy generation facilities.
