Why insulation testing is necessary?

All live conductors of electrical appliances and installations must be insulated to prevent electric shock hazards from inadvertent contact or fire hazards from short circuit and equipment damage. In addition, a low insulation resistance can result in a leakage current which causes a waste of energy that increases the running costs of the installation.

Insulation resistance must be checked by applying a higher voltage than the normal working voltage to ensure there is sufficient insulation.

Periodic testing is also important to ensure that insulation of installations or appliances is not deteriorating. Foreign matter and mechanical factors like wear or breakage may reduce insulation resistance. Regular tests can detect possible fault in insulation.
