Product Description

Handheld Partial Discharge Detector for High-Voltage Switchgear

Darui Electric recommends for you:

Features

1.The handheld partial discharge detector for high-voltage switchgear displays ultrasonic and TEV partial discharge waveforms and yellow, green, and red three-segment readings on the same interface.

2. It measures the magnitude of partial discharge using transient earth voltage (TEV) and ultrasonic methods, with units in dBmV.

3、This handheld partial discharge patrol and positioning instrument uses a color LCD screen, providing a more intuitive and user-friendly display.

4、It is equipped with headphone monitoring; in ultrasonic mode, real-time monitoring of partial discharge signals can be achieved through headphones.

5、The display can show waveforms in real time and store valuable waveforms. Test data is automatically stored, facilitating review of test records and subsequent analysis of test data.

6、It has high signal amplification and sensitivity; the signal receiving range is an effective distance of 15m.

7、It features a red laser aiming with moderate intensity, strong focusing capability, accurate positioning, safe and reliable, simple and practical.

8、It can detect and locate insulator discharge on towers and creepage of exposed cable terminations.

9、This handheld partial discharge tester is mainly used to detect partial discharge in high-voltage switchgear.

10、It is easy to use, small in size, light in weight, and portable.
