The role of capacitance in capacitive voltage transformers 2

3. Electric field sensing: The electric field in the capacitor changes with the voltage being measured. Therefore, by measuring the voltage changes at both ends of the capacitor, the size and changes of the input high voltage signal can be accurately obtained, achieving monitoring and control of the power system. diode

4. Insulation protection: Capacitors used in CVTs usually have good insulation performance, which can effectively isolate high and low voltage systems, avoid accidents such as arc breakdown, and improve the safety and stability of the system.

Overall, capacitors play a crucial role in capacitive voltage transformers, not only achieving voltage reduction and signal transmission, but also ensuring stable and safe operation of the system.  diode
