Classification of High Voltage Testing Methods

Classification of High Voltage Testing Methods: Classification of High Voltage Testing Methods are divided into two groups: Power Frequency Withstand Voltage Impulse withstand voltage Tests These tests together ensure the over voltage withstand capability of an apparatus. The Basics Terminology techniques of the technical terms are discussed here. In test codes and standard specifications, certain …

Partial Discharge Measurements

Partial Discharge Measurements: Earlier the testing of insulators and other equipment was based on the insulation resistance measurements, dissipation factor measurements and breakdown tests. It was observed that the dissipation factor (tan δ) was voltage dependent and hence became a criterion for the monitoring of the high voltage insulation. In further investigations it was found …
