• Abnormal load detection
• Motor operating condition monitoring

These functions allow the relay to protect motors against both electrical faults and abnormal mechanical operating conditions.

4. Structural Composition

The GE 369 relay generally consists of several major functional sections:

Microprocessor Control Unit

Processes sampled electrical signals and executes motor protection algorithms.

Current Measurement System

Receives current signals from CTs and calculates motor current, imbalance, overload, and fault conditions.

Protection and Output Circuits

Provides configurable relay outputs for trip, alarm, and control functions.

Human-Machine Interface

The front panel incorporates an LCD display, LEDs, and pushbuttons for viewing measurements, alarms, status information, and configuration parameters.

Communication Interface

Provides serial communication for integration with supervisory control systems and for relay configuration and data retrieval.

5. Product Features

Comprehensive Motor Protection

Multiple protection functions are integrated into a single relay, reducing the need for separate protection devices.

Motor Monitoring

The relay can monitor important motor operating parameters and provide useful information for maintenance and troubleshooting.

Event and Fault Recording

Operating events and fault information can be recorded to assist with post-fault analysis.

Flexible Configuration

Protection settings, trip levels, alarm thresholds, and control logic can be configured according to the motor and application requirements.

Industrial Reliability

The 369 series is designed for industrial motor protection applications and can be used in demanding electrical and process environments.
