Improve power factor allows users transformers, switches and cable equipment under ... while reducing power loss and drop in the electrical network.

In electrical systems, the improvement of the system capacity needs to be always performed to keep up with the development of the additional charge. In the power transmission grid, lines of wire always have to adjust the operation to prevent overload, which is a frequent occurrence, if the overload occurs too long, it may lead to drop in tacks, connections and heat emission, increase the deflection threatening to the system.

National electricity system with backbone parts including electric transmission network and distribution, is one of the most important infrastructure systems of national economy. Vietnamese electric network has experienced many stages of formation and development with various brands of device, from those of XoViet Union to European and North America
