Intro：This series of metering boxes are improved on the basis of similar products. They are suitable for electric energy measurement in outdoor AC power systems with rated frequency of 50Hz, rated voltage of 10kV and 6kV. They are ideal substitutes for old-fashioned oil-immersed products.
This series of products is composed of a combination of voltage and current transformers and a measuring instrument box. The transformers are equipped with three independent voltage and current transformers, which are installed in phases A, B, and C. The outer wall of the combined transformers is equipped with a power transformer The watt-hour meter, and the combined junction box for testing, shall be covered with the meter box to prevent electricity theft during operation.
