Description
Overview
GAOTek underground transmission line tester is used to test the distance between fault position to the measured transformer when aerial transmission line in short circuit or open circuit. It applies to the overhead transmission line under 35kV, which with permanent single -phase earth fault or disconnection fault; make the tests for fault line in the substation. It can measure the exact distance, confirm the broken poles, convenient for maintainers to check the fault, shorten the repairing time. This device only can be used if the measured line is power off. It is small in volume, easy to carry, with AC or DC battery, diagram and digital display, easy to operate.
