Description
Overview
GAOTek handheld DC grounding fault locator can be configured in different sensors to detect partial discharge in all electric equipment. The humanized human-computer interface facilitates data management of different devices. Built-in ultrasonic sensor and transient ground voltage sensor can be externally connected with special sensors such as transformer, GIS, overhead line, cale, etc. non-intrusive detection method is adopted, which is more convenient than the traditional pulse partial discharge detector, because there is no need to cut off power and configure additional high voltage source during the test and the test bandwidth range is 30 kHz to 2.0 GHz, applicable to the detection principle of various frequency bands.
Features
- The test bandwidth range is 30 kHz to 2.0 GHz
- Built- in ultra sonic sensors
- Transient ground voltage sensor
- Non invasive detection method
- Humanized human-machine interface
