760-P5-G5-S5-HI-A20-R
Product Overview
The GE 760-P5-G5-S5-HI-A20-R is a high-performance digital feeder protection relay developed by GE Multilin, officially launched in the early 2000s. As a core device of the classic Multilin 760 series, it is professionally designed for medium and low-voltage power feeder line protection and intelligent management. This integrated relay integrates power system protection, high-precision electrical metering, fault recording and remote communication functions. Adopting high-sensitivity current sampling and industrial anti-interference design, it supports real-time monitoring and rapid fault response of power feeder lines. The HI configuration and R suffix enhanced version features higher environmental adaptability and operational stability. After decades of global power grid field verification, it has become a mainstream standard device for power distribution system construction, maintenance and renovation projects.
Core Product Features
The 760-P5-G5-S5-HI-A20-R supports multi-channel 5A current signal input, including phase current, zero-sequence current and sensitive ground current acquisition, realizing comprehensive monitoring of feeder line operating status. It adopts universal wide-range AC/DC dual power supply (70–265 VAC / 88–300 VDC), adapting to complex and unstable substation power supply environments without additional conversion equipment. It integrates complete feeder protection logic, covering overcurrent protection, ground fault protection, phase unbalance protection and over/undervoltage protection, effectively avoiding power line faults and equipment damage. Equipped with multiple communication interfaces, it supports Modbus RTU, Modbus TCP/IP and DNP3.0 industrial protocols for efficient data transmission. The built-in waveform capture and event recording functions provide accurate data support for post-fault analysis and system optimization.
System Compatibility & Technical Advantages
This feeder relay features excellent power system compatibility, perfectly matching standard 5A CT/PT sensors used in power distribution networks. It can be seamlessly connected with substation SCADA monitoring systems, DCS platforms and upper power grid management software, realizing remote parameter configuration, real-time data monitoring and fault alarm uploads. The industrial high-impedance anti-interference design effectively resists strong electromagnetic interference and power surge in substation environments, ensuring long-term stable operation. Different from ordinary protection devices, it integrates protection, metering and communication functions, simplifying on-site equipment layout and reducing system construction costs. With mature hardware design and ultra-low failure rate, it has strong replaceability and is the preferred spare part for aging power distribution protection system upgrade and maintenance.
Industrial Application Scenarios
The GE 760-P5-G5-S5-HI-A20-R feeder protection relay is widely applied in power grid and industrial power supply scenarios. It is mainly used for safety protection and operational monitoring of medium and low-voltage feeder lines in urban substations, industrial park power distribution rooms, petrochemical power supply systems, metallurgical power distribution networks and water treatment power supply systems. It undertakes core tasks such as real-time operating parameter monitoring, line fault protection, electrical energy metering and system linkage control, ensuring safe, stable and uninterrupted power supply of power distribution systems.
