What is the 11kV transformer?
What is the 11kV transformer?
33kV to 11kV transformers steps down the the voltage to a safe level, which is then distributed via 11kV feeders to homes and businesses. The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area.
What is a transformer switchgear?
switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Which transformer is in 33 11kV substation?
To step down the 33kV primary voltage to 11kV suitable for distribution purpose. One 33kV/0.415 auxiliary transformer was also needed to supply the substation with reliable AC power.
What is the rating of transformer used in 33 11kV substation?
Introduction to Electricity Distribution System 11 KV Primary Distribution system is emanating from 33/11 KV Substations feeding power supply to HT Consumers and 11000/440-220 volts Distribution transformers for supply to LT Three Phase and Single-Phase consumers.
What is the meaning of 33 11 kV?
Thus, when a substation is of rating 66/11 kV, means substation has been designed to receive 80 MVA on 66 kV and it will distribute the received power on 11 kV. Again, substation of rating 33/11kV means, the substation has been designed to receive 5 MVA of power at 33 kV and it will distribute the same on 11 kV.
What is the current in 11kV line?
Take a 11kV/415v, 500KVA distribution system. Then maximum current on HV side = 500/{sqrt(3) * 11} = 26.24 A. maximum current on LV side = 500/{sqrt(3) * 0.415} = 695.6 A.
What is the transformer rating?
Transformer ratings are measured in volt-amperes (VA) or kilovolt-amperes (WA). Engineers rate power transformers according to the maximum output voltage and current they deliver.
