SF6 Standard Capacitor

The standard capacitor is widely used in the high voltage test. It can be connected with tan delta bridge to measure the dielectric loss of test object. For example, during dielectric loss test, it is used as standard, and compare the capacitance and tgδ value with measuring capacitor, cable, bushing, insulator, transformer winding and insulation materials.
