The ***6KHP Surge Comparison tester designed by Jabbals is the most comprehensive tester to check the quality of electrical windings. This instrument is highly reliable, accurate and cost-effective. It is extremely versatile and a valuable tool to easily test the motors in the motor shop or field. As with a new enhanced feature of DSO interface it can easily store the test results that can be printed when required. This Surge tester has been widely appreciated by motor manufacturers worldwide and has immensely improved the quality of the LT motors in the industry. The Surge Comparison tester checks the strength of ground insulation that consists of enameled insulation. It detects the insulation failures such as turn-to-turn shorts, layer-to-layer shorts, coil-to-coil shorts, winding-to-winding shorts, and phase-to-phase shorts. Open circuit and ground detection are other benefits of surge testing. The Surge tester uses the principle of impedance balance to test the quality of electrical windings.The Surge tester works as a capacitive-discharge system. A capacitor is charged with high voltage and then discharged into the winding, through a solid state assembly. This sequence is repeated thus stressing the insulation of the winding with high voltage pulses. The resulting voltage decay pattern of two winding is then displayed on the CRT. The waveform pattern will be perfectly superimposed for good windings but in case of a defective winding a double wave pattern will appear on the screen as one wave pattern from the good winding plus the erratic pattern from the faulty winding.
