Metering Combined Transformer-JZZY1-10

Metering Combined Transformer

JZZY1-10

Composed of three single-phase potential transformers (PT) and current transformers (CT), both the PT and CT are electromagnetic types. This type of transformer is suitable for use in a three-phase AC system with a rated frequency of 50 Hz and rated voltages of 6 kV or 10 kV for energy metering. It is installed on the high-voltage side of the power supply transformer. The meter box is equipped with three-phase active energy meters and reactive energy meters, which are used to directly measure the active and reactive energy in high-voltage lines.
