It is outdoor, single phase and oil capacitor voltage transformer, which is used for metering and relay protection of 35~220KV, 50Hz system, its capacitor divider is also used as coupling capacitor in carrier wave coupling device in power line unit.
The capacitor divider is making up of one or several coupling capacitors to series.
H.V. terminal is at top of capacitor divider, medium and low voltage terminal is in electromagnetic unit for leading from magnetic on lowest H.V. capacitor chassis.
