imported resin, long-life outdoor and high-accuracy
10kV electrical energy meter measurement
Description
This model combined transformer is one kind of outdoor energy metering device, it is one newest dry type power metering tank specially designed for non-oil renovation of power network, which replaces old type oil-immersed product. This product owns many advantages as small volume, large capacity, steady insulated performance, anti-pollution and non-require maintenance etc.
This product is composed of two sets single-phase wholly insulated voltage transformers, forming three-phase “V/V" wiring mode, and two current transformers are separately series connected to A and C phase, moreover, the secondary coil of current transformer owns tap, through which gains different current changing and has metering more accurate. For the super quality anti-aging insulated material is adopted inside this product, and its outer appearance is vacuum-cast by outdoor epoxy resin, doesn't need any special maintenance, so it just needs regular cleaning of appearance pollution.
