Coupling Capacitor

A coupling capacitor, also a capacitive divider, is a key device in power systems for voltage measurement and partial discharge tests. Taking the TAWF-50000/70 model as an example, it adopts an insulated shell oil-immersed capacitor structure, composed of a shielding ring, capacitor body, mobile chassis, and low-voltage arm. It can also serve as a coupling capacitor during partial discharge tests, with a measurement uncertainty of <+1% (certified by the measurement department).
