Hipot test is used to assess what aspect of electrical equipment?

• A. High-current rating test; assesses conductor size
• B. Low-voltage safety test; assesses insulation with leak detection
• C. High-potential insulation test; assesses insulation integrity by applying high voltage and measuring leakage
• D. Mechanical endurance test; assesses connector durability

Answer: (C)

Hipot test, short for high-potential test, applies a voltage well above normal operating levels between conductors and their insulation to stress the dielectric. The idea is to see if the insulation can withstand voltage without breaking down or allowing excessive leakage. By measuring the leakage current at this high voltage, you can assess the insulation’s integrity and dielectric strength. This is a safety-oriented check focused on insulation health rather than the conductor’s current-carrying capability or the device’s mechanical durability.
