What is an Insulation Tester?
An insulation tester, also known as a megger, is a specialized instrument used to measure the insulation resistance of electrical equipment or wiring. It’s commonly employed in the maintenance and troubleshooting of electrical systems to ensure their safety and reliability.
The principle behind insulation testing is to apply a high-voltage direct current (DC) to the insulation being tested and measure the resistance. This high voltage is used to stress the insulation and reveal any weaknesses or faults. The higher the insulation resistance, the better the condition of the insulation. Conversely, a low insulation resistance indicates potential issues... Read More
