Abstract
High-voltage (HV) testing utilizes the phenomena in electrical insulations under the influence of the electric field for the definition of test procedures and acceptance criteria. The phenomena—e.g., breakdown, partial discharges, conductivity, polarization and dielectric losses—depend on the insulating material, on the electric field generated by the test voltages and shaped by the electrodes as well as on environmental influences. Considering the phenomena, this chapter describes the common basics of HV test techniques, independent on the kind of the stressing test voltage. All details related to the different test voltages are considered in the relevant Chaps. 3–8.
