The QCT17 is installed on the ground wire of the surge capacitor. For this, the case of the surge capacitor has to be insulated from the ground, with just the ground wire connected to the main ground through the QCT17. The measurement is contact free, No galvanic connection to the high voltage terminals is made. The CT has an inner diameter of 17mm this allows standard earth wires (typically 16mm2) to be used. The maximum current of 25A before the CT goes into saturation makes the QCT17 the ideal PD sensor for practically all surge capacitor ranges.
The QRC40 Rogowski Coil is designed to acquire high frequency current pulses generated by partial discharge and is an ideal sensor for installation around high voltage power cables and bushings that are less than 40mm in diameter.
The QRC85 Rogowski Coil is designed to acquire high frequency current pulses generated by partial discharge and is an ideal sensor for installation around high voltage power cables and bushings.
