SG2008 Automatic 12kV Capacitance & Dissipation Factor Test Set is designed to measure dissipation( Dielectric Loss Angle tand tgδ ) or power factor ( cosφ ) 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.
