How is insulation resistance calculated and tested?

We should all be familiar with Ohm's law. If we apply a voltage across a resistor and then measured the consequential current flow, we can then use the formula R=U/I, (where U=Voltage, I=Current and R=Resistance) to calculate the resistance of the insulation. This is a very basic method indeed and we must be aware of the many different types of current which are consequence to the insulation resistance test. These include capacitive charge current , polarization current, leakage current and conduction current.

Insulation resistance is calculated using an insulation resistance tester. Generally, two leads are connected into a circuit in order to carry out the test. How and where these two leads are connected will differ depending on what the test subject may be. A third lead, which may or may not be available for your tester, will connect to a guard terminal. The guard terminal acts to allow you to be selective in evaluating specific electrical components in a large piece of plant machinery, for example.
