What Is a Dielectric Strength Test?
The dielectric strength test, also known as the insulation resistance test, is a critical examination designed to evaluate the insulation resistance of electrical equipment under its operating voltage.
This test involves applying a voltage to the significantly higher equipment (typically 10 to 20 times) than its normal operating voltage, for a specific duration. The primary objective is to ascertain that the equipment’s insulation is robust and effective.
By conducting this test, it’s possible to identify products with inadequate insulation resistance, which could lead to insulation failure and potentially hazardous accidents. Thus, the dielectric strength test is essential for ensuring the safety and reliability of electrical equipment and components.
