Coupling Capacitors & AC Voltage Dividers
Coupling capacitors are used for the decoupling of PD current pulses together with measuring impedances placed in series in standard measuring circuits to convert into voltage pulses for analysis with a PD detector according to IEC 60270. The coupling capacitor also acts to drop the test voltage to a safe, measurable value.
Coupling Capacitor Models:
HV capacitors for PD or AC measurements (≤ 200 kV): 9230 Series
HV capacitors for PD or AC measurements (≤ 200 kV): 9231 Series
High voltage capacitors for PD or AC measurements (≥ 300 kV): KK Series
25 kV PD Coupler with measuring impedance and HV filter: 9230/25/1-PD
30 kV PD Coupler with measuring impedance and HV filter: 9230/30/9-PD
HV capacitor for PD or AC/DC measurements: 9241/100/1
