Which of the following is NOT a dielectric testing type mentioned?

• A. Dielectric Breakdown Test
• B. Dielectric Withstanding Test
• C. Insulation Resistance Test
• D. Continuity Test

Answer: (D)

Dielectric testing is about how insulation handles electric stress and how much leakage it allows, rather than just whether a conductor is connected. The test that doesn’t fit as a dielectric test is the one that checks a conducting path. It verifies whether a wire or component forms a complete circuit and usually uses a low voltage to confirm continuity, not to assess insulation performance. The other tests directly probe insulation: one measures the voltage at which insulation breaks down, another applies a high voltage for a period to ensure insulation can withstand it, and the last checks insulation resistance to gauge leakage. So continuity testing isn’t a dielectric test because it focuses on conductor connectivity rather than insulation properties.
