KK Series Coupling Capacitors & AC Voltage Dividers
The Haefely KK high voltage capacitor series consists of 1 or more modular units, built into fiberglass-reinforced epoxy tubes. Their applications include coupling capacitor for PD measurements, measuring AC voltages in the power frequency range, providing a base load for high voltage AC resonant test systems, and attenuating interferences coming from the HV supply with the optional high voltage filter. The standard base frame is fitted with castors for mobility, and upon request, large and heavy versions can be equipped with air cushions.
