Overview
The NK is a series of SF6 insulated higly stable nominal capacitors available in the voltage range from 300 to 1 200 kV. It is used together with a power factor / tan delta measuring instrument as a comparison standard for exact measurements of capacitance and tan d of HV equipment like cables, transformers, bushings, capacitors, etc. The capacitors are provided with a top electrode making possible partial-discharge-free interconnections to other elements of the HV circuit. The SF6 insulated standard capacitor is designed for indoor service and is mobile on castors.Features
- Highly stable capacitance with no influence from atmospheric pressure and humidity
- Very low internal dissipation factor
- Partial Discharge free
- Simultaneous tan d and voltage measurement (Dual) possible upon request.
- Secondary unit for high Voltage AC measurement under request
