GE SR750-P1-G1-S1-HI-A20-R Feeder Management Relay

The GE SR750-P1-G1-S1-HI-A20-R Feeder Management Relay is a powerful device designed for distribution feeder system management. Here are some details about this relay:

I. Main Functions

Simplify processes and extend system life: Through its multiple protection functions, it reduces the stress on system components and extends the service life of the system.

Multiple protection functions: including overcurrent protection and over/under frequency protection, which protect system components in the event of potential threats and ensure stable operation of the system.

Metering and data logging functions: The ability to determine values such as voltage, frequency, watt-hour cost, load trip percentage, and operating and maximum demand provides important data for system management and troubleshooting.

II. Structural Features

Front panel design: It is roughly divided into four parts, including a 40-character LCD display, a keyboard, LEDs, and an RS232 port. The LCD display can display various system values (configurable by the user), the keyboard is used for manual set point configuration and general navigation, the LEDs are used to indicate system status and active processes, and the RS232 port allows direct connection to a computer running EnerVista 750 software.

Conformal coating: Optional conformal coating provides additional protection against corrosion, temperature, dust and humidity, making it particularly suitable for harsh environments.

III. Operation and safety

Set point management: Set point programs can be created, edited or deleted from the front panel of the relay or through GE Multilin's EnerVista 750 software. The plug-and-play functionality of the software makes setup quick and easy.

Security measures: Additional security measures are implemented through password protection to prevent unauthorized adjustment of set points. This password protection applies to both manual editing from the front of the relay and editing through the EnerVista 750 program.

IV. Application and compatibility

Application scenarios: The SR750-P1-G1-S1-HI-A20-R is typically mounted on a 19-inch panel and can be used as a stand-alone unit or with other relays in the 750/760 series.

Compatibility: Compatible with EnerVista 750 software, which provides an advanced user interface to make set point management easier.

V. Summary

GE SR750-P1-G1-S1-HI-A20-R feeder management relay is a device that integrates simplified processes, multiple protection functions and high integration. It provides a comprehensive and efficient solution for distribution feeder system management through its powerful functions, flexible operation and reliable safety.
