This series of products is composed of two parts: voltage and current combined transformer and measuring instrument box. There are two independent voltage and current transformers installed in phase A and phase C in the transformer. The outer wall of the combined transformer is equipped with power and reactive power. The meter, the joint connection box used by the Brain Man experiment, is covered with a meter box to prevent electricity theft during operation. The inner core of this type of product is cast with epoxy resin, and the outer shell is made of steel barrels to avoid direct damage to the epoxy resin cast body caused by ultraviolet rays of the sun.
