Description: As partial discharge occurs, the ultrasonic wave will spread in the form of spherical wave. This equipment is designed for fast detection of the partial discharge of switchgears and ring main unit through receiving the ultrasonic signal.

Features:

1. Adopt large color LCD screen

2. The ultrasonic and TEV PD wave form show in the same interface with the yellow, green and red warnings.

3. Using the TEC and ultrasonic to detect partial discharge in dBmV

4. Earphone monitoring mode available, real-time monitoring of PD signal.

5. The test data can be stored automatically, more convenient to check record and future analysis.

6. High sensitivity, wide signal receiving range, the effective is 15m.

7. Red laser marking, accurate location, safe and reliable
