What is difference between 11kV and 33kV?

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. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.

Why do we use 11kV to 33kV?

It is cheaper to generate at a relative lower voltage and then step it up for transmission. Hence, most power generating plants are designed to operate at 11KV. To generate at 33KV, the size of the motor might be twice as large as the size of 11KV generator.

Is 11kV phase or line voltage?

For instance, in an 11kV three-phase system, the voltage between any two live conductors gives a line voltage of 11kV while the voltage between any live conductor and neutral (or earth) gives a phase voltage of 6.35kV.

How do I know my 33KV line?

In a transmission line, if three pieces of disc insulators per phase are connected, then the KV of the transmission line is 33KV. For the 33KV transmission line, generally, Four Pole structure is used.

Why is 11kV generated?

Generally, high voltages like 66kv or more than that are generated when the power is transmitted over larger distance. When the power is to be transmitted to shorter distances, power stations use 11kv. The specific reason for that is as the distance to be covered increases, so does the resistance of the wire.

Why is 11kv generated?

Why 11kV is 240v generally used?

The voltage is generated at 11 KV because it requires less insulation in comparison to the generation of voltage at above 11 KV. The high voltage rotating machine may not be so reliable as compared to the low voltage rotating machine.

What voltage are power lines?

Transmission lines carry high voltage electricity, typically at 345,000 volts, over long distances between the power generation plant and customers.

What is the difference between 33kV and 11kV power lines?

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. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.

What is a 3333kv to 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. Many people question why the voltage is as high as 33kV in the first place.

What is the difference between 66/11 kV and 33/11kv substation?

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.
