Megger testing is a type of electrical testing that is used to measure the insulation resistance of electrical cables and other electrical equipment. It is also known as a 'megohmmeter test' or simply a 'megger test.' The purpose of megger testing is to determine the condition of the insulation on electrical cables and other equipment. Insulation resistance is an important factor in the performance and safety of electrical systems, as it helps to prevent electrical shocks and fires. During a megger test, an electrical current is sent through the insulation of the equipment being tested, and the resistance of the insulation is measured. If the insulation resistance is too low, it may indicate that the insulation is damaged or degraded, which could lead to electrical hazards. (https://mechatrofice.co...)
