The capacitors are of sturdy and rugged and are for indoor operation. Insulation is reinforced epoxy fiberglass tube filled with oil.
Decouples partial discharge signals from device under test (DUT) when used with an optional measuring impedance (AKV) or with PD detector DDX 9160/9161 with integrated internal AKV.
Measures AC voltages in the industrial frequency range (when used with an optional secondary unit (SEK)).
Attenuates interferences coming from the HV side and improving signal to noise ratio (SNR) of the PD measuring circuit (together with an optional HV filter).
The standard design includes a base frame with swivel castors for mobility, termination box with BNC connector including surge protection and an appropriate upper toroid.

Advantages
• Save room in the HV laboratory – with our compact all in one solution, high voltage capacitor, measuring impedance (optional), secondary unit (optional) high voltage filter (optional) in one single unit, the number of necessary devices for performing a test are drastically reduced
• Increase your sensitivity – with the optional HV filter, interferences from the HV power supply are sufficiently suppressed and signal to noise ratio of the test circuit is improved
• Highest accuracy results – large measurement frequency bandwidth, high stability in capacitance values with frequency and temperature guarantee a consistent and reliable measurement

• Power and distribution transformers
• Instrument transformers
• Rotating machines
• Switchgears (MV/HV/GIS)
• Bushings
• Cables
