9230 Series Coupling Capacitors & AC Voltage Dividers
The Haefely 9230 high voltage capacitor series consists of a modular HV capacitor, which fitted with an appropriate measuring impedance or AC secondary unit, can be used for partial discharge measurements or AC voltage measurements. For PD measurements, a measuring impedance is placed in series with the coupling capacitor and the PD pulses are then captured and transferred to a PD detector. Models are available up to rated voltage 200 kV.
