The surge current testing device HCS 3-30 is used for surge current testing of capacitor windings. The capacitor to be tested is on an adjustable voltage, 0,005 - 3000 V, charged and then discharged via a triggerable switch.
External partial discharges at high-voltage electrodes (corona) possess an acoustic spectrum, which extends to the ultrasonic region. Because of the strong directivity of high-frequency sound waves, ultrasonic detectors do not only allow detection, but also the localization of corona discharges, for instance, in switchyards, high-voltage test set-ups or transmission lines. The ultrasonic detector USD 38O1/38O2 operates at a frequency of approx. 33 kHz that is particularly suitable for external partial discharge detection. The combination of a highly directional ultrasonic microphone and a parabolic reflector system allows an exceptional directivity of the acoustic sensitivity. The microphone output signal is picked up by a selective amplifier and transformed into an audible signal. This allows a simple evaluation of the partial discharge intensity by headphones.
