beeindia.gov.intransmission is the next stage from power plant to transport A.C. power over long distances at voltages like; 220 kV & 400 kV. Where transmission is over 1000 kM, high voltage direct current transmission is also favoured to minimize the losses. Sub-transmission network at 132 kV, 110 kV, 66 kV or 33 kV constitutes the next link towards the end ...

Step-up transformers are typically sized to the generat-ing units, with modest losses at normal operating levels. If, however, they carry more power than their original intended capacity, losses increase sharply. This can be a
Training Report on 220 to 132kV Substation
www.123seminarsonly.comvoltage (11 KV or 6.6 KV) at the power station is stepped up to high voltage (Say 220KV to 132 KV) for transmission of electric power. Similarly near the consumer’s localities, the voltage may have to be stepped down to utilization level. This job is again accomplished by suitable apparatus called sub-station. 2.1 About the substation :-
