High Voltage Leakage Tester

Because the insulation resistance and reactance of the stray capacitance is so high the ac test current can be simplified to the leakage current at 250 v times the ratio of hi pot test voltage to 250 v.

High voltage leakage tester.

In most cases the device is stressed to twice its normal operating voltage. Voltage withstand testing is done with a high voltage source and voltage and current meters. The basic function of hipot tester is to monitor excessive leakage current to ground. It applies the necessary voltages to a device and monitors leakage current.

In this test the insulation of a product stressed to a greater extent than under normal operating conditions should not be breached for the product to pass. If the test voltage is 3000 then the test current would be 3000 250 x 0 5 or 6 ma. Hioki s electrical safety testers withstand voltage testers insulation resistance testers protective continuity testers and leakage current testers comply with iec 61010 1 jis c 1010 1 and other applicable standards laws and regulations. While the test method is referenced in the united states pharmacopeia usp chapter on container closure integrity cci usp.

A single instrument called a pressure test set or hipot tester is often used to perform this test. This is a high voltage test that stresses the insulation of an electrical product far 80 m. 1207 perhaps the best benefit of high voltage leak detection is the platform flexibility. The technology easily scales from lab bench to 100 inline testing applications at high production speeds ensuring product quality throughout the product lifecycle.

If the insulation of product can withstand a much higher voltage for a given time then it can withstand normal voltage for its whole life.
