Recently, Huawang successfully completed the shipment of a switchgear partial discharge and temperature online monitoring project for power equipment condition monitoring applications.
The project includes:
- 4-in-1 partial discharge sensors
- IoT concentrators
- Wireless temperature sensors
The system is designed to provide real-time monitoring of partial discharge activity, equipment temperature, and environmental conditions, helping improve the safety and reliability of power systems.
4-in-1 Partial Discharge Sensor for Comprehensive Monitoring
The core device used in this project is the 4-in-1 partial discharge sensor, integrating:
- UHF (Ultra High Frequency) detection
- TEV (Transient Earth Voltage) detection
- Ultrasonic (AA) detection
- Temperature & humidity monitoring
Compared with conventional single-parameter monitoring solutions, the multi-technology integrated design enables more accurate fault identification and insulation condition assessment.
The solution is widely used for:
Why Online Partial Discharge Monitoring Matters
Partial discharge is one of the earliest indicators of insulation deterioration in electrical equipment.
If not detected in time, it may lead to:
- Insulation failure
- Switchgear breakdown
- Cable faults
- Unexpected power outages
As smart grid technologies continue to develop, more substations and industrial facilities are deploying online partial discharge monitoring systems to achieve predictive maintenance and reduce operational risks.
Key Features of the Monitoring System
Multi-Parameter Integrated Detection
The system simultaneously collects:
- Partial discharge signals
- Ultrasonic signals
