What kind of test is high voltage testing?
High voltage testing can be broadly classified into testing of insulating materials (samples of dielectrics) and tests on completed equipment. The tests carried out on samples of dielectric consist generally of the measurement of permittivity, dielectric loss per unit volume, and the dielectric strength of the material.
How is high voltage used to test insulation?
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. 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.
What kind of voltage is used for hipot testing?
The majority of safety standards allow the use of either ac or dc voltage for a hipot test. When using ac test voltage, the insulation in question is being stressed most when the voltage is at its peak, i.e., either at the positive or negative peak of the sine wave.
What's the name of the high potential HV test?
Hi-Pot test is a contraction for high potential HV testing. Hipot Test is short name of high potential (high voltage) Test and it is also known as Dielectric Withstand Test. Hipot test makes surety of no current will flow from one point to another point.
