Introduction to Electrical substation ?C Instrumentation .

May 02, 2020??? A substation is a facility which is used to step-up or step-down the voltage in the utility power lines, voltage will be stepped up if the power is transmitted through long-distance transmission lines and it will be stepped down when the power is to enter the local distribution line.In general, an electrical substation is a place which transmits electricity from one part of the production .

Why in transmission substations 400kV is not directly .

The reason for 400kV being step down gradually through 132kV, 66kV and then to 33kV is because direct stepping down would mean a huge transformer at the reciever end. Now a 400kV transmission line tower could be more or less something like this. I.
