Which transformer is used for 11kV line?
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 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.
How transformer is manufactured?
Both High Voltage (HV) and Low Voltage (LV) windings are done using Coil Winding Machines. The Copper or Aluminium strips/wires used in winding are meticulously selected for its quality to give the best output. The Copper or Aluminium strips/wires are paper covered and acts as insulators.

Why is 11kV 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….If it is not related to the form Factor, What is it then?
| Sending Voltage | Receiving Voltage |
|---|---|
| 20kV x 10% = 22kV | 20kV |
| 30kV x 10% = 33kV | 30kV |
| 60kV x 10% = 66kV | 60kV |
Is 33KV a transmission or distribution?
The 33 kv substation systems are distribution substations that take electricity from transmission substations and then supply the same to the end consumers after stepping down the high voltage to a safe level.
Is 33kV a transmission or distribution?
How can you tell if a line is 11kV and 33kV?
For the 11KV transmission line, generally Double Pole(DP) structure is used. In a transmission line, if three pieces of disc insulators per phase are connected, then the KV of the transmission line is 33KV.
What is considered high volume manufacturing?
What is High-Volume Manufacturing? High-volume manufacturing is the same as mass production: fabricating large quantities of goods in short periods of time. Goods that are produced in high volume often have little or no variation.
What is a 33kV transformer converted to 11kV?
It’s a step-down transformer which convert 33kv to 11kv, the primary voltage is 33kv, the secondary voltage is 11kv. This transformer equipped with a on load tap changer to easy change the output voltage.
What is 12 MVA power transformer?
The 12 MVA power transformer was manufactured by us in 2005, the rated power of the transformer is 12000 KVA. It’s a step-down transformer which convert 33kv to 11kv, the primary voltage is 33kv, the secondary voltage is 11kv. This transformer equipped with a on load tap changer to easy change the output voltage.
What is a dry type 11kV transformer?
These 11kV transformers are considered to be easily maintained, reliable, and robust due to the structure having no moving (or serviceable) parts. Suitable for industrial, commercial and hazardous applications the dry type transformers offer a long lifespan, efficiency and accuracy.
What type of transformers are suitable for LV MV HV?
Powerstar dry type or ‘air cooled’ distribution transformers are suitable for LV MV HV indoor and outdoor power distribution applications such as data centres, environmentally sensitive areas, marine and offshore.
