Introduction
Capacitor voltage transformers are widely applied to AC power systems, used for measurement, control, protection and high-frecuency carrier communication.
Product mix
A capacitive voltage transformer consists of a capacitor unit and an electromagnetic unit. The capacitor unit is composed of a capacitor voltage divider and a coupling capacitor. The capacitor voltage divider and coupling capacitor are both high-voltage ceramic shells, with a capacitor core
installed inside the shell. The core is composed of several components in series, and an external oil built-in metal expander is used for temperature compensation reactor, damper,etc. The secondary terminal is led to the terminal box on the outer wall of the fuel tank through a wiring board.
