Nickname: Handheld Partial Discharge Detector; Partial Discharge Detector; Ultrasonic Partial Discharge Detector
Feature:
1.Simultaneous interpreting PD signals of almost all electrical equipment with different sensors；
2. Humanized man-machine interface facilitates data management of different equipment；
3. Built in ultrasonic sensor and transient ground voltage (hereinafter referred to as TEV) sensor, which can be connected with special sensors such as transformer, GIS, overhead line and cable；
4.The non-invasive detection method is adopted, so there is no need to cut off power and configure additional high-voltage source in the test process, which is more convenient than the traditional pulse partial discharge detector；
5.The test bandwidth range is 30kHz ~ 2.0GHz, which is applicable to the detection principle of various frequency bands；
