Description
Overview
Mobile High Voltage Underground Digital Cable Fault Locator GAOTek offers mulitple functions. It offers safe, quick and accurate test. The instrument applies the method of low voltage pulse and HV Flashover. It can test all kinds of faults especially on the Flashover and High Resistance fault testing and without burning through. If it is equipped with locating instrument, it can exactly point out the location of the fault. It uses the tech of high speed data sampling, the speed of A to D is 100 MHz and makes resolution ratio of 3.28 ft and testing dead zone of 3.28 ft. The testing results automatically show by wave form and data on the large LED. It is easy for viewing. It doesnot need special training for operations.
