Impulse Test

Impulse Voltage	200V-5000V
Area Comparison	Layer shorts increase coil power loss and resonance damping; the resonance amplitude and total wave area decrease. Comparing the area detects layer short circuits.
Area Differential	Sums the difference between reference wave and DUT wave. A layer short reduces inductance and shifts the wave phase, increasing the differential area.
Waveform Comparison	A tolerance band around the reference wave; the DUT passes if its wave stays inside. Judges amplitude and phase of the resonance wave.
Corona	Counts corona discharges caused by insulation defects during the pulse test.
Flat	Layer shorts make the waveform tremble; the instrument quantizes and compares this trembling.

Open full datasheet

With the 3-in-1 transformer test system, many components can be tested in one work step. The system consists of a transformer tester (626x), an impulse winding tester (7721) and a HiPot tester (7605). In one test sequence, all coils of a transformer can be tested with all low voltage tests, the impulse winding test (surge test) and the high voltage tests DC 6kV and AC 5kV. The transformer tester (model 6265/6266/6267, test frequency 200kHz/500kHz/1MHz, 20 channels) has a basic accuracy of up to ±0.1%. The impulse winding tester (7721) has 21 programmable impulse voltage channels and offers various comparison modes (Total Area, Differential Area, Corona, Laplacian, Comp). The HiPot tester (7605) supports AC 5000V, DC 6000V and insulation resistance 1000Vdc.
