Can type capacitor voltage mutual inductor

A voltage mutual inductor of tank capacity type consists of sealed tank body, high voltage electrode, medium voltage electrode, sleeve of outgoing wire and electromagnetic unit. It is featured as forming high voltage arm capacity C1 by cylindrical surfaces between high voltage and medium voltage electrodes, forming medium voltage arm capacity C2 by cylindrical surfaces between medium voltage electrode and sealed tank body, using two said arm capacities C1 and C2 to form capacity voltage divider.
