What Is Hipot Tester?

A hipot tester, also known as a dielectric withstand tester, is an instrument that applies a high voltage to an electrical device or component to assess insulation integrity and test limits. The purpose of hipot testing is twofold:

  • Firstly, it is a safety check conducted during manufacturing to verify that a product’s design specifications and performance match its rated voltage levels without breakdown or arcing.
  • Secondly, dc hipot tester confirms that the fabrication process has yielded insulation systems capable of withstanding high voltage transients that may occur during operation.
  • Thirdly, to perform a hipot test, a voltage much higher than the normal operating voltage is applied to the unit under test. Any leakage current or arcing that occurs indicates defective insulation unable to meet specifications.

Any Difference Between An Insulation Test & A Hipot Test?

  • Firstly, an insulation test evaluates device insulation quality on site, whereas a ac hipot tester performed in the factory checks design and manufacturing quality with safety as priority.
  • Secondly, an insulation test applies a moderate voltage measuring ohmic resistance and leakage current versus norms. It detects deterioration weakening winding insulation allowing low resistance paths.
  • Thirdly, a hipot test identifies nonlinear breakdown dangers by subjecting the system to known voltages validating any currents stay beneath set minima. Hipot testing safeguards quality control pre-consumer use.
  • Fourthly, routine insulation checks on location assess compliance and endurance over time under an acceptable voltage.
  • Fifthly, mandatory ac dc hipot tester in manufacturing examine each item under electrical stresses far exceeding operating limits while capping any flows to protective ceilings.
  • Sixthly, an insulation test screens for degradation disrupting current insulation restraint within standard margins at an applicable potential.
  • Seventhly, stringent factory hipot tests guarantee original strength and construction methods before widespread deployment.
