Test Technology - Hipot / Dielectric Testing
ATI utilizes the latest concepts in Hipot/Dielectric testing.
Important Standard features incorporated in ATI Test Systems include:
Capacitance Compensation which separates the real resistive current from the sometimes very large capacitive current which flows as a result of winding to core capacitance. This
feature permits maximum leakage current limits to be set lower and provides better analysis of the Stator insulation.
Ramped Turn-on of Hipot Voltage eliminates the high current inrush associated with the instantaneous application of high voltage to the part under test. If a ground is detected during the voltage ramp-up, Hipot power is removed before damage can occur.
True RMS Measurement of both leakage current and applied voltage is more accurate due to the requirement to measure parameters that contain out-of-phase components.
Arc Detection is a feature that detects arcing that is sometimes observed at the peaks of the test voltage. This arcing, because of the short duration, may not be of sufficient magnitude to cause the RMS leakage current to exceed the maximum leakage current limit.
