Profile:
KDYD2835KV interturn impulse withstand voltage tester is a kind of test instrument which adopts pulse waveform comparison method to simulate the overvoltage of the second coil or winding with high voltage shock wave and distinguish the waveform difference of the second winding by oscilloscope. It can quickly and correctly judge the coil or winding turn insulation corona discharge, local or interphase short circuit, open circuit, wiring errors, coil balance and other faults.
Features:
KDYD2835KV interturn impulse voltage tester is suitable for winding interturn insulation detection of large and medium-sized high voltage, AC-DC motor with rated voltage of 10000V and below; It can also be used to detect the insulation between turns of transformer winding and electrical coil winding. Due to the motor and transformer windings due to the insulation structure and insulation materials are inconsistent, especially the operator's different technological level, in the winding, wiring, scraping, joint end shaping, handling and other processes will cause different degrees of insulation damage, so that the winding there are various forms of inter-turn insulation failure, therefore, inter-turn insulation is the weak link of the motor and transformer.
