Measurement of Insulation Resistance - Electrical Volt
WebNov 30, 2024 · An insulation resistance (IR) test measures the total resistance between any two points separated by electrical insulation. The test, therefore, determines how effective the dielectric (insulation) is in resisting the flow of electrical current. What is a bad reading on a Megger test? What is a bad reading on a Megger test? WebOct 15, 2024 · The second category is resistance, which is intentionally extremely high to insulate and stop current between conductors. Insulation can be difficult to measure with conventional multimeters, using mega ohm-meters or ‘meggers’ instead to determine proper insulative properties. Figure 1.
