What is the difference between 11kV and 33kV transformer?
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 11kV 22kV 33kV 66kv?
But we already know that there are some voltage drop due to the resistance of the transmission lines. For this reason, they transmit 10\% extra voltage. Sending Voltage = 10kV x 10\% = 11kV. While the receiving end voltage are 10kV due to voltage drop.
What is the output of a transformer?
A transformers output voltage is greater than the input voltage if the secondary winding has more turns of wire than the primary winding. The output voltage is stepped up, and considered to be a “step-up transformer”. If the secondary winding has fewer turns than the primary winding, the output voltage is lower.
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.
How do you identify a 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.
How do you calculate the input voltage of a transformer?
Input and output power
- Electrical power is calculated by multiplying voltage (in volts) by current (in amps).
- If a transformer is 100\% efficient, then the input power will equal the output power.
- V P is input (primary) voltage.
- I p is input (primary) current.
- V s is output (secondary) voltage.

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.
Why is the voltage of a transmission line 33kV?
Many people question why the voltage is as high as 33kV in the first place. The reason is that the higher the transmission voltage, the lower the transmission losses will be. Therefore, the longer the distances that the power needs to be transferred, a higher voltage is used to reduce the transmission losses.
What is the technical specification of 33/11kv sub-station (10 &16 MVA)?
