The 7720 Impulse Winding Tester uses a very high voltage impulse to stimulate the device under test (DUT). It analyzesthe decay waveform to detect changes in material, shorted and damaged windings and other errors. Long term decay of a winding can also be detected.The system used ensures that the component is tested but not damaged during the analysis process.The shape of the waveform is dictated by the Q factor,inductance and stray capacitance of the winding. High Q shows as a slow decay and the frequency of thewaveform is determined by the inductance and straycapacitance of the DUT. Importantly, the short highvoltage pulse causes no damage to the device under test.
