What is hi-pot tester?

A hi-pot tester (also known as a dielectric withstand tester) is an instrument used to verify the electrical insulation of a product or component. It applies a high voltage, typically significantly greater than the normal operating voltage, between the conductors and the chassis or other accessible parts. This test determines if the insulation is adequate to prevent electrical breakdown or arcing under normal and surge conditions. It's commonly used in manufacturing to ensure product safety and regulatory compliance, and during maintenance to detect insulation degradation.
