A test that determines the largest potential that can be applied to a conductor without breaking down the insulation (see Dielectric Strength).
A test that applies a high voltage to a conductor to assure the integrity of the surrounding insulation. See "Dielectric Breakdown".
High Potential Test. A test to determine if the breakdown voltage of a circuit or component exceeds the minimum requirement.
A test to determine if the breakdown voltage of a transformer or power supply exceeds the minimum requirement. It is performed by applying a high voltage between the two isolated test points.
A dielectric test performed by applying a high voltage for a specified time to two isolated points in a device to determine adequacy of insulating materials.
