About the 750-P1-G1-S1-HI-A20-R

While distribution feeder system management can be a difficult task, General Electric Multilin’s 750-P1-G1-S1-HI-A20-R streamlines the process and extends system life. Equipped with numerous features that protect distribution feeder systems, Multilin’s Feeder Management Relay reduces strain on system components and reduces troubleshooting times through its metering and data logging capabilities.

The relay’s front panel is broken up into approximately four sections: the 40-character liquid crystal display, the keypad, the LEDs, and the RS232 port. The 40-character liquid display is alphanumeric and indicates various system values (configurable by the user) when not in active use. The keypad allows for manual setpoint configuration and general navigation of the relay. The LEDs can indicate when problems arise in the system and also keep users informed on active processes. Finally, the RS232 port allows easy, direct connection between a computer running the EnerVista 750 software and the relay. 

The 750-P1-G1-S1-HI-A20-R includes a metering function that can determine values such as voltage, frequency, watthour cost, percent of load-to-trip, and running and maximum demand. The relay can use its metering function to trigger an alarm when the breaker maintenance threshold is exceeded. Alarm can be indicated through the relay’s twenty aforementioned LEDs.

Additional security measures can be implemented through passcode protection to prevent unauthorized adjustments of setpoints. This password protection works for both manual editing from the front of the relay and editing through the EnerVista 750 program. For manual entering of setpoint configuration, a jumper must be installed on the rear terminal.
