The medium-voltage electric energy generated by power plant is transmitted to high-voltage power grid through MV/HV main transformer.
In general, the electric power is transmitted to primary substation through overhead line.
In HV/MV primary substation, the electric power is converted into medium voltage from high voltage.
in MV/MV primary substation, the electric power is transmitted to several secondary substations at lower level. The circuit breakerplays an important role in power transmission and distribution.
