High voltage breakdown testing procedure.

The lower the resulting breakdown voltage the poorer the quality of the transformer oil. This test procedure covers the general high voltage tests required for the high voltage high power alternating current generator described as one of the selected power sources in u s. Dielectric breakdown testing may be required during the development of assemblies used in critical applications. Repeat this test procedure for all circuit phase conductors testing each phase to ground and each phase to each phase.

It can also be used on a random sample basis to verify that the maximum voltage is not changing. Dielectric breakdown testing is used in product design and qualification stages. The test is sensitive to arcs or corona so it often finds terminal spacing problems over mold problems tolerance errors in idc cables or any problem that might produce arcs. Breakdown voltage testing procedure.

The test is a means to qualify a device s ability to operate safely during rated electrical conditions. The testing procedure is very simple. High voltage is applied across a specimen of insulation or equipment under test by means of a high voltage transformer. If the insulation holds the voltage the device is deemed to have passed the test.

Designs and manufactures industry leading high voltage test equipment for proof testing diagnostic testing high voltage breakdown testing and preventative maintenance testing. A dielectric withstand test or pressure test high potential or hipot test is an electrical test performed on a component or product to determine the effectiveness of its insulation the test may be between mutually insulated sections of a part or energized parts and electrical ground. The test is usually performed at about 75 of the typical breakdown voltage and is done as a safety net. It helps establish the maximum voltage of the design.

To assess the insulating property of dielectric transformer oil a sample of the transformer oil is taken and its breakdown voltage is measured. A resistor is connected with series with the transformer to limit the short circuit current in the event of breakdown occurred in the device under test. The test involves placing an extra high voltage across the insulation barrier of the device for one minute. The transformer oil is filled in the vessel of the testing device.

At the end of the one minute test switch the hipot tester from the high potential test mode to the voltage measuring mode to confirm that the circuit phase conductor and voltage of hipot tester are now reading zero volts. Air force technical document afapl tr 82 2057 volume 2 high voltage testing. However if the applied voltage leads to the sudden breakdown of the insulation material and allows current to flow the insulation is determined to be. By contrast the point of withstand voltage testing is to check dielectric strength to see whether an insulation breakdown will occur.
