1. For GIS partial discharge analysis.
2. Two signal channel. UHF and acoustic sensor.
3. Portable and easy operation.

Portable GIS Partial Discharge Detector

By using UHF 0.3-3GHz principle, attached on the surface of GIS, the UHF sensor collects the inside discharge
signal of impure gas, suspension potential and solid insulation material. It detects the insulation deficiency
without cutting off the power and the expert diagnosis system analyzes the fault character and location so as to
avoid electricity accident. It is necessary for the smart grid and routine maintenance.

Features

1. This PD detector is for daily patrol inspection, high efficiency, easy operation.

2. Two signal channels. One detects the partial discharge signal, another excludes the disturbance
signal like corona discharge in the air and mobile phone communication.

3. Automatically alarm when detecting the partial discharge inside the GIS.

4. Attached on the surface of GIS without open the asset.

5. Electromagnetic disturbance resistance.

6. Noise sensor improves the liability of partial discharge identification.

7. High sensitivity up to 5PC.

8. Wider sense range than ultrasonic sensor, less detection points.

9. AC/DC dual power. Full charged battery can last for 8 hours detection.
