INSULATION RESISTANCE TESTING AND TRACING

Описание к видео INSULATION RESISTANCE TESTING AND TRACING

Why do we test the insulation resistance of electrical circuits? After all, it’s just plastic, what can go wrong?

In this video we look at the reasons for testing electrical circuits, and then look at some established methods to carry out insulation resistance tests. How do we prepare for testing, what must we do to the circuits even before we begin.

And then we will look at the numbers involved. What is a good result, a pass; and what is a fail?

We will show you how to calculate parallel resistances to obtain an accurate value for the whole of the installation so that decisions can be made regarding the ongoing safety and reliability.

And if we do find problems on a circuit or within the installation, what can we do about it? So finally, we will introduce an excellent method for tracing insulation resistance faults in a circuit.
