Core Protection and Control Function

The GE 750-P5-G5-HI-A1-R-E is a Feeder Management Relay from the General Electric Multilin series. This advanced relay provides comprehensive monitoring, protection, and control for electrical distribution feeders. It utilizes dual microprocessor architecture for reliable and responsive system safeguarding. Consequently, it ensures the stability and safety of medium-voltage power distribution networks.

Dual-Processor Architecture and Communication

This relay integrates a Motorola 68332 32-bit processor for analog signal handling and relay control. A second Grid Connect DSTni-LX 186 16-bit processor manages the display, LEDs, and communication interfaces. The 750-P5-G5-HI-A1-R-E supports multiple serial communication protocols including RS232, RS422, and RS485. Furthermore, its design includes robust overload withstand capabilities for demanding electrical environments.

Detailed Technical Specifications

Engineered for industrial and utility applications, the relay operates reliably in high-humidity conditions. Its construction meets Pollution Degree II standards for use in typical industrial atmospheres. The following table details its key electrical, communication, and physical parameters.

Key Feature and Application Distinction

Unlike its 760 series counterpart, this specific 750 model does not include an automatic reclosing function. It is therefore ideally suited for cable feeder applications or systems where automatic reclosing is not required. The GE provides essential overcurrent, earth fault, and other protective functions. Therefore, it is a key component for protecting industrial plants, commercial facilities, and utility distribution circuits.
