Top 10 AC DC Hipot Tester Manufacturers in the world 2026 - Blog

Introduction to AC DC Hipot Tester

An AC DC Hipot Tester, also known as a high - potential tester, is a crucial piece of equipment used in electrical testing. Its primary function is to verify the integrity of electrical insulation in various electrical devices and components. By applying a high voltage (either AC or DC) to the device under test for a specific period, the tester can detect any potential insulation weaknesses, such as cracks or breakdowns. This helps prevent electrical shocks, short - circuits, and other safety hazards in electrical systems, ensuring the reliability and safety of electrical products. AC hipot testing is often used for simulating real - world operating conditions, while DC hipot testing is useful for detecting certain types of insulation defects more effectively.
