SG2008 Automatic 12kV Capacitance & Dissipation Factor Test Set is designed to measure dissipation (Dielectric Loss Angle tgª-) or power factor (cosª+) in heavy electromagnetic interference environment such as in power plants or substations. Also it can be used in laboratory for high accurate test. The test set is all-in-one structure: including precision digital bridge, 12kV/200mA frequency conversion power unit, reference capacitor (CN), and other electronic circuits. An external power supply can expand the test range. True portability is realized by the lightweight. Simple usage is realized by the full automation. High performance is realized by the digital process.
We can also provide the professional solutions and equipments for: withstanding voltage testing, c & tan-delta (power factor) testing, partial discharge (PD) testing and impulse voltage testing.
This is the most advanced automatic version of the c&df sets within our product range. The automatic 12kv 200ma test set integrates the high voltage power source and the measuring bridge into one single compact unit. It is designed to measure dissipation factor and capacitance in heavy electromagnetic interference environment such as in power plants and substations. Using digital filters it eliminates interference signal to specimen signal by a ratio as high as 2:1. It can also be used in laboratory for high accuracy tests on high voltage bushings, transformer windings, shunt reactors, current transformer, capacitor voltage transformer (cvt), grading capacitors of circuit breakers, surge arrestors and generator windings.
