Product Number:GE Multilin 369-HI-R-0-0-0-0-E  keep relay

Product Overview

The 369-HI-R-0-0-0-0-E of GE Multilin is a protection relay used in power systems and belongs to the GE Multilin 369 series. This series of relays is mainly used for protection, control and monitoring in medium and low voltage substations, industrial power distribution systems and power generation facilities. The following is its detailed analysis:

I. Model Structure Analysis

Meaning of segmentation

The line protection relay series number of 369 GE Multilin focuses on the protection of feeders, transformers and capacitor banks.

The abbreviation of "HI High Integrity" indicates that this relay meets strict reliability standards and is suitable for critical power systems.

The functional identification of "R Relay" indicates the product type.

0-0-0-0 usually represents default configuration parameters (such as the number of channels, communication protocols, etc.), for specific details, please refer to the manual.

E Enhanced (Enhanced version) or a specific firmware version, which may contain additional functions or upgrades.

Ii. Core Functions and Features

Protection function

Overcurrent protection: Three-stage overcurrent protection (instantaneous break, fixed time limit, inverse time limit), and directional components can be configured.

Grounding fault protection: Detect grounding current to prevent equipment damage and electric shock to personnel.

Overvoltage/undervoltage protection: Monitor abnormal voltage and protect sensitive equipment.

Frequency protection: Prevents equipment damage caused by system frequency fluctuations.

Control and Monitoring

Circuit breaker control: Supports remote opening and closing operations and has anti-trip function.

Data acquisition: Record real-time data such as current, voltage and power, and support fault recording.

Event record: Store fault events and operation records to facilitate fault analysis.

Communication interface

Supports protocols such as Modbus RTU/TCP, DNP3, IEC 61850, etc., and can be connected to SCADA or distributed control systems.

It is equipped with an Ethernet or RS-485 interface to achieve remote monitoring and configuration.

Reliability design

Redundant power supply: Supports dual power input (AC/DC) to ensure continuous operation in case of power failure.

Self-diagnostic function: Real-time monitoring of the internal status of the relay, and automatic alarm when a fault occurs.
