Capacitor insulation resistance

WebMay 22, 2024 · Insulation resistance of electrolytic capacitor DC voltage is applied to the capacitor and a leakage current is generated. The ratio between the two is called the insulation resistance. When the capacitance is small, it mainly depends on the surface state of the capacitor. WebInsulation Resistance:Insulation Resistance (IR) is the DC resistance measured across the terminals of a capacitor, represented by the parallel resistance (Rp) shown in Figure 1. For a given dielectric type, electrode area increases with capacitance, resulting in a decrease in the insulation resis-tance.
