High voltage metering box
1. Scope of application
High voltage metering box is mainly composed of a combination transformer and an electric metering box. The combination transformer consists of two or three single-phase voltage transformers and current transformers. It uses transformer mineral oil as the insulating medium. The primary and secondary outlet terminals are all installed on the panel with porcelain sleeves; the electric metering box is installed on the side of the combined transformer. It consists of an active meter and a reactive meter. It is suitable for three-phase rated frequencies of 50Hz and 60HZ. AC line 11KV, 23KV, 35KV power grid system, which has the advantages of high measurement accuracy, light weight, easy installation, and prevention of electricity theft.
