369-HI-R-M-F-E-H-E Motor Management Relay

GE Multilin 369-HI-R-M-F-E-H-E  Motor Management Relay

Overview

The GE Multilin 369-HI-R-M-F-E-H-E is a high-performance protective relay and control device tailored for medium-to-high voltage power systems. Engineered to ensure reliable fault detection, circuit protection, and system monitoring, this model integrates advanced protection algorithms, real-time data acquisition, and flexible communication capabilities.

It serves as a critical component in industrial, utility, and commercial power distribution networks, combining rugged hardware with configurable software to adapt to diverse system requirements.

Functional Features

Advanced Protection Capabilities

Supports comprehensive protection elements: overcurrent (51), earth fault (50N), distance protection (21), directional overcurrent, and transformer differential protection.

Enables automatic reclosing, breaker failure detection, and adaptive protection schemes for precise fault isolation.

Configurable time-current characteristics ensure coordination with upstream/downstream devices.

Real-time Monitoring & Data Logging

Measures electrical parameters (voltage, current, power, frequency) with high-precision sensors (±0.5% accuracy).

Captures fault waveforms, event sequences, and disturbance records for post-fault analysis (supports up to [X] event logs).

Displays real-time status via front-panel LCD and LED indicators.

Flexible Communication Interfaces

Equipped with serial ports (RS-232/485), Ethernet (10/100BaseT), and optional fiber optic ports.

Supports industry-standard protocols: IEC 61850. DNP3. Modbus, and IEEE C37.118 for SCADA integration.

Enables remote configuration, monitoring, and firmware updates via web interface or GE Multilin ToolSet software.

User-configurable Operation

Intuitive HMI for local setup and diagnostics.

Customizable protection zones, alarm thresholds, and control outputs.

Multi-level password protection for secure access and configuration.
