Web1 sep. 2024 · Type 1 tests are intended to detect defects in a cable system’s insulation in order to improve service reliability after the defective part is removed and appropriate repairs are performed. These tests are usually achieved by applying moderately increased voltages across the insulation for a prescribed duration of time. WebA Megger test is done by an insulation tester resistance meter to verify the electrical insulation of a wire. Megger Test A Megger meter is also called a Mega-ohm meter. This is because the unit of the meter is in Mega-Ohms. From a small wire used at home to large wires used in transformers, the resistance is checked by the Megger test.
