High Voltage ,Test, (Dielectric Voltage-withstand ,Test,) This ,test, is carried out by applying a significantly higher than operating voltage to the device under ,test,. 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. In most cases, the device is stressed to twice its normal operating voltage.

What is Circuit Breaker Testing and How is it Done ...

A megger instrument applies a known DC voltage to a given wire for a given ,period, of time in order to ,test, the resistance within the ,insulation, on that particular wire or winding. It is vital that voltage is employed as the resistance checked with an ohmmeter may differ when there are no report of potential differences.

Very low frequency (VLF) withstand ,testing, is the application of an AC sinusoidal waveform, generally at 0.01 – 0.1 Hz, to assess the quality of electrical ,insulation, in high capacitive loads, such as cables. During the ,test, cables are subjected to a ,test, voltage significantly higher than what they experience during normal operating conditions.
