The Dielectric Voltage Test, also known as a Hi-Pot test or insulation withstand test, assesses the electrical insulation strength of equipment or materials. It involves applying a significantly higher voltage than the operating voltage for a specified duration to detect weaknesses or defects in the insulation. A successful test indicates the insulation can withstand transient overvoltages and provides a safety margin for normal operation, preventing electrical breakdown and ensuring user safety. This crucial test is a standard procedure for quality control, safety certification, and maintenance of electrical systems and devices.
