Home >> Technical >> External PD Calibrator

External PD Calibrator Type HVS 998/0011

The calibration of a PD test circuit is a necessary step in the test procedure. The system is fed with a calibration pulse of a known value of apparent charge.

Battery powered
Synchronization with mains frequency
Adjustable apparent charge

Design Features

The calibrator Type HVS 998/0011 feeds a short duration current pulse of a known magnitude through the terminals of either the de-energized test objet [direct calibrationJ or the coupling device (indirect calibration) The PD detector will be adjusted to the value of the apparent charge given by the calibrator . Synchronization with the line Frequency is supported through optical coupling. The calibrator complies with IEC 270.
