This detailed SOP explains the correct field practices

A Megger test is an electrical test used to measure the insulation resistance of electrical circuits, cables, and equipment. The test is typically performed with an instrument called a Megger, which is a type of insulation resistance tester. It applies a high voltage (usually between 250V to 5kV) to the electrical component and measures the resistance of the insulation. The purpose of a Megger test is to ensure that the insulation around conductors is intact and effective in preventing electrica
