What is Dielectric Withstand Testing for wire harnesses??
This is the test of wire harness dielectric strength.
There are two elements of the withstand voltage test: test voltage and test time.
As an analogy, let's assume that the test target is a wood board. Suppose the wood board is supported at two points and weights are placed on it. As long as the weight is light, nothing will change on the wooden board. It will gradually bend as the weight is increased. If you add more weights, the wooden board will not be able to withstand the weights and will break. This is the state where insulation breakdown has occurred. Also, if the wooden board is left bent by weight, it will break over time. This is also due to dielectric breakdown. It may be easier to understand if the weight is the test voltage and the time is the test time.。
