Pole-mounted capacitor 3370 series

gascalibrationreference

The 3370 is a series of standardized SF6 insulated higly stable nominal capacitors available in the voltage range from 5 to 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. • 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
