Application Scenarios
- Industrial Motors: Protection and control of pumps, fans, compressors, and conveyors.
- Power Generation: Motor-driven auxiliary systems in power plants.
Performance Parameters
- Accuracy: High-precision current and voltage measurement.
- Response Time: Fast fault detection and tripping to minimize motor damage.
Material Composition
- Enclosure: Ruggedized metal enclosure for harsh industrial environments.
- Internals: Industrial-grade microprocessors and precision analog front-end.
Structural Characteristics
- Design: Rack-mount or panel-mount configuration.
- Interface: Front-panel display and keypad for local monitoring and configuration.
Working Principle
Continuously samples motor current, voltage, and auxiliary inputs. It compares these values against programmed protection curves and setpoints, initiating control actions or trips when abnormal conditions are detected.
Installation Requirements
- Install in a clean, dry environment with adequate ventilation.
- Use properly shielded cables for CT and VT connections.
Usage Precautions
- Configure protection settings according to motor nameplate data and system studies.
- Perform regular testing to verify relay functionality.
