High voltage short circuit current ≥ 3mA, is the measurement of large transformers, transformers, generators, high voltage electric motors, power capacitors, power cables, surge arresters and other ideal insulation resistance test equipment.
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.
