Remark: English version is available for all the testers.
The partial discharge won't make complete short-circuit electrode electric discharge. The discharge amplitude is usually very small. But it will cause the insulation performance declining and the electric equipment falling to fault. Non-Invasive discharge detecting provides rapid and easy solution, identifying potential insulating fault that leads to suddent power off and personnel injury.
Technique Parameters
1. Application: Adopts non-invasive detecting way, detect and locate the partial discharge fault of high-voltage equipment.
2. Transducer configuration
Standard: Ultrasonic sensor(UA), geoelectric wave sensor(TEV)
Optional: Special sensor for transformer, ultra-high frequency sensor for GIS, sensor for high-voltage cable, or customization as per customer.
3. Detecting theory: Ultrasonic way(UA), geoelectric wave way(TEV) or Ultra-high frequency way(UHF).
4. Detecting frequency zone
Ultrasonic: 40~200kHz
Geoelectric wave: 3~100mHz
Ultra-high frequency: 300~2000mHz
5. Measurement range
Ultrasonic: -90~80dB
Geoelectric wave: -80~10dBm
Ultra-high frequency: -80~10dBm
6. Sensitivity: The minimum 10pC(depend on the distance between sensor and discharge power)
7. Transducer
