PD -
Shanghai Jiuzhi Electric Co., Ltd.
Partial discharges (PD), as defined by IEC60270, are localized dielectric discharges in a partial area of a solid or liquid electrical dielectric insulation system under high-voltage field stress. It can be caused by discontinuities or imperfections in the insulation system. PD testing thus gives an indication of deterioration of the insulation and is an indicator of incipient faults. In general PD will occur in systems operating at voltages of 3000 V and above; it should be noted though that in some cases PD can also occur at lower voltages.

GBJS Series -
Shanghai Jiuzhi Electric Co., Ltd.
Dissipation factor tand standards are designed for checking the accuracy of measuring capacitance and dissipation factor tand. A tand standard is basically a standard capacitor in series with a resistor. To avoid excessive resistance values, a capacitor with a negligible dissipation factor is used. Samgor has determined the following tand values for a measuring frequency 10-200H.

SGS H & SGS V -
Shanghai Jiuzhi Electric Co., Ltd.
The sphere gap type SGS H or SGS V can be used for Impulse, AC and DC voltage calibration according to the IEC 60052 recommendation.The spheres are arranged vertically or horizontally, one being mobile. In the vertical version the mobile sphere is remotely adjusted by using an electrical drive. In the horizontal version, both spheres are mounted on columns of insulating materials, hence enabling to superimpose impulse AC and DC voltages.
