Description

GE UR8GH is an industrial control module developed by General Electric.It is specially designed for power system protection and automation control and belongs to the core component of the GE Multilin general relay series.The following is a comprehensive description of its core functions and technical characteristics:

I.Core functions

Sensitive grounding protection

It provides high-precision grounding fault detection,and the sensitivity is ten times higher than that of the basic model.It is suitable for ground fault protection of complex power systems.

Support differential protection,phase separation protection and other functions,and monitor current and voltage signals in real time through CT/VT modules(current transformers/voltage transformers)to ensure system stability.

Modular configuration and expansion

Through EnerVista UR software,the protection scheme can be highly customized,support the drag-and-drop debugging environment,and simplify the configuration process.

Compatible with Ethernet communication(Modbus TCP/IP,SRTP protocol)to realize remote monitoring and data transmission.

Health diagnosis and safety

Built-in advanced health diagnosis function,continuously monitor CT/VT signal integrity,DC voltage level and hardware status to ensure data accuracy.

Support automatic short-circuit mechanism,automatically trigger protection when the relay is moved out of the shell to prevent accidental power outage or short circuit risk.

II.Technical parameters

Electrical characteristics

Working voltage:220V DC(some versions support 5V DC input and 3.3V DC output).

Processing speed:15Hz,program capacity 2MB,data capacity 1MB.

Input/output interface:support 4-20mA analog input,digital signal input/output,compatible with industrial bus protocols(such as Profibus DP,EtherCAT).

Environmental adaptability

Operating temperature:-40°C to+70°C,to meet the requirements of the harsh industrial environment.

Protection level:IP65(some versions),anti-vibration and electromagnetic interference(in accordance with IEC 61000 standard).

Physical specifications

Weight:about 1.13 kg,modular design,support rack or panel installation.

III.Application scenarios

Power system protection

It is used for overload protection,short circuit protection,overvoltage/overvoltage protection for generators,transformers and busbars,and real-time monitoring of voltage,current,frequency and other parameters.

Industrial automation control

Integrated into the PLC or DCS system,it controls the start-stop and interlock operation of contactors,circuit breakers and other equipment.

Process control

Monitor temperature,water level and other analog signals to achieve precise regulation and fault warning of industrial processes.

IV.Design advantages

High reliability:Redundant design(such as redundant Ethernet modules)is used to ensure the fault tolerance of the system.

Flexible expansion:Support multi-module collaboration(such as UR-8NH CT/VT module)and expand to 24 analog signal inputs.

Intelligent maintenance:realize firmware upgrade and configuration management through EnerVista software to reduce maintenance costs.
