The main purpose
It is suitable for three-phase AC lines with rated frequency of 50Hz and rated voltage of 6, 10, and 35kV. Outdoor direct measurement of active and non-condensing energy in the line
The main function
This product is mainly composed of a combined transformer and an electroplating meter box. The combined transformer is composed of two or three single-phase voltage transformers and current transformers, and 25# transformer oil is used as an insulation cut-off. The first and second occurrences are installed on the panel with a porcelain sleeve. The electroplating meter box is installed on the side of the combined transformer and consists of a constant active watt-hour meter and a reactive watt-hour meter. Kuyou has the advantages of high metering accuracy, light weight, easy installation, and anti-stealing lights.
