The general indicators for measuring electrical performance are as follows:
• Dielectric strength, the ratio of the voltage to the thickness of the sample when the sample is broken between the electrodes under a continuously increasing voltage.
• Dielectric constant, the ratio of the capacitance when plastic is used as the medium and the capacitance when vacuum is used as the medium.
• Dielectric loss, a parameter that characterizes the energy loss of the insulating material under an AC electric field, is the cotangent between the applied voltage and the current through the sample.
• Volume resistivity and surface resistivity.
• Arc resistance, which means the resistance of plastics to arcs and sparks. The arc resistance of plastics is often expressed in terms of scorch time (s).
