Overview

GAOTek underground power cable fault pre-locator is designed to provide quick, accurate, and safe measurement solutions for underground power cable fault pre-locating. Measure the power cable of different sections, different media of various materials, short circuits, open circuit short line fault, and the low and middle resistance fault. Great for KV substations, civil power supply systems, and power energy source applications. Use the induction method to measure the cable fault waveform, which can be sampled with any high-voltage pulse generator. At the same time, it can be directly connected to our high-voltage pulse generator for direct sampling on the high-voltage side, making the waveform more accurate and analysis easier.
