Low voltage equipment is built for rated voltages not exceeding 1000 V AC 1200 V direct current.They are used not only in central power stations, but also in industry and domestic sectors at a very large scale.
By means of such equipment the distribution of electricity on large stretches is made effective. It also makes a great supply of electricity to individual consumers.
Transmission of high-voltage lines in DC, unlike the widely used mode of transport using high-voltage line AC is a process for electricity transmission as a DC voltage of 100-1000kV.
