Jusco nmcc scada(avinash kumar) - SlideShare· High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgears in substations are located on both the high- and low-voltage sides of large power transformers.
