RZJ - 45Interturn impact withstand voltage testerproductFeatures

RZJ - 45The interturn impact withstand voltage tester isadoptParallel resonance mode of capacitors and inductorsSimulate overvoltage detection of two coils or windings using high-voltage shock wavesdisplayatOn the storage oscilloscopeTwo coilsThe method of waveform comparison,Identify faulty coils.Compared to the series resonance method, the parallel resonance method is more suitable for testing single coils, especially coils with fewer windings.Suitable for rated voltage15,000VInsulation testing of windings between turns for large, medium, high voltage, AC, and DC motors of different sizes; It can also be used for inter turn insulation detection of transformer windings and electrical coil windings. Due to the inconsistent insulation structure and insulation materials of motor and transformer windings, especially the different levels of operator craftsmanship, insulation damage can occur to varying degrees in processes such as winding, wire embedding, wire scraping, joint end shaping, and handling, resulting in various forms of inter turn insulation faults in the windings. Therefore, inter turn insulation is a weak link in motors and transformers.

RZJ - 45Interturn impact withstand voltage testerThe basic principle is to detect the symmetrical balance of the impedance of the test sample，Non destructive simulation test of equivalent overvoltage on motor and transformer windings using shock wave comparison method with high-frequency and high-voltage pulses,By using the oscilloscope of the instrument itself to observe and compare waveforms, it is possible to intuitively, quickly, and correctly test winding turn to turn short circuits and various impedance imbalance faults.
