Profile:
KDYD2850KV interturn impulse voltage tester is suitable for winding interturn insulation detection of large and medium-sized high voltage, AC-DC motor with rated voltage 15000V 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.
Features:
KDYD2850KV interturn impact voltage tester is based on the basic principle of detecting the symmetrical balance of the impedance of the subject. It adopts the shockwave comparison method to carry out the equivalent overvoltage simulation test of the motor and transformer windings with high frequency and high voltage pulses, and uses the oscilloscope of the instrument to observe the waveform comparison and analysis. Can directly, quickly and correctly test winding short circuit and various impedance imbalance fault.
