RZJ - 40The 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 voltage13500VInsulation 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.

Technical parameters of RZJ-40KV inter turn withstand voltage tester

Interturn voltage testerIt adopts the pulse waveform comparison method,A testing instrument that simulates the detection of overvoltage in two coils or windings using high-voltage shock waves, and uses an oscilloscope to distinguish the waveform differences between the two windings. It can not only quickly and accurately diagnose various faults such as insulation corona discharge between coils or windings, local or phase to phase short circuits, open circuits, wiring errors, coil balance, etc., but has also been widely used in related industries.

RZJ40KV Interturn voltage testerSuitable for rated voltage 13500V Insulation 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.

RZJ40KV Interturn voltage testerIt is based on the principle of detecting the symmetrical balance of the impedance of the test object. The shock wave comparison method is used to conduct non-destructive simulation tests on the equivalent overvoltage of motor and transformer windings using high-frequency and high-voltage pulses. The oscilloscope of the instrument itself is used to observe and analyze the waveform, which can intuitively, quickly and correctly test winding turn to turn short circuits and various impedance imbalance faults.
