Description
Overview
Portable Multi-Pulse TDR Cable Fault Locator GAOTek is applicable to testing all types of faults of power cables with 35kV and lower voltage, test kV cables/wires with above double-core (including coaxial),test open circuit and low resistance faults, calibrating length of cables/wires and transmission speed of electric wave in the cables. At the Flashover sample test method, HZ-501B cable fault locator, working with cable fault pin-pointer,HZ-504 cable route tracer, HZ-535 or 4 series High Voltage pulse generator, to complete the measurement of cable fault by “flashover method”.
