Research on the Impact Divider Performance Test for Measuring Inter-turn Insulation of Motor Stator

In the process of research on the project of calibration method of motor stator electrical property testing device,we developed a impact resistance divider,which consist of the measure of equipotential shielding ,the use of non inductance resistor and the distributed capacitance regulating technology.It is used for measuring impulse voltage peak value of motor stator inter turn insulation,and measuring the time to peak.After the test, the error of resistor divider voltage ratio is less than 0.5%,rise time less than 100ns,and it meets the measurement requirements.
