Abstract:
A calibrator apparatus for calibrating the performance of partial discharge measurements at electrical components, such as high voltage cables or transformators, comprises a housing (1) and an external electrode (4) to be mounted at the housing (1). A control unit (2) generates a defined charge pulse (QS) depending on a stray capacitance (CS) of the external electrode (4) against ground, which is supplied to the electrical component.
