The leakage of the current to earth should not exceed 0.02% of the full load current.īefore performing insulation resistance test between installation and earth the conditions to be fulfilled for the position of the main switch, fuses, switches, and other points should be as under:. It also ensures that the insulation is sufficient enough to avoid any possible leakage of current to earth. This test is performed to know the standard of insulation of wires and cables used in the installation.
Insulation Resistance Test between Installation and Earth
These tests will receive the attention of the owner before any possible undue damage occurs.To ensure that it is free from faults and is as per electricity rules.To know the cause of failure of a particular circuit or circuits or equipment and to locate the exact position of break down.the main reasons, to test a new electrical installation or house wiring before it is switched on to the mains are as follows: All new completed electrical installation should be tested before connection to the supply, to ensure that the installation is technically sound and free from any possible short circuits, etc.
