Combined CT-VT Metering Units

• Combined CT-VT Metering Units and Cubicles are used for metering at high voltage side of the distribution system.
• Combined CT-VT Metering Units are Oil Immersed type whereas Combined CT-VT Metering Cubicles are Dry type in construction.
• Combined CT-VT Metering Units consist of 03 nos. single phase polyester / paper insulated CTs and 01 no. three phase polyester / paper insulated VT enclosed inside a metal tank filled with Transformer oil.
• Combined CT-VT Metering Cubicles consist of 03 nos. single phase resin cast CTs and 01 no. three phase resin cast VT enclosed inside a metal cubicle in the lower compartment. The three phase energy meter is installed in the upper compartment.
