33kV To 11kV Transformers

33kV-to-11kV

33kV to 11kV transformers step down 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. 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, the higher the voltage is used to reduce the transmission losses. Once it has reached a substation, the voltage is then stepped down.

At Johnson & Phillips, we deal with a range of high-voltage applications that require an experienced team to handle such voltage. The 11kV lines are used in residential areas and are what feed the local transformers, which then distribute 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.

Below is a graphical example of a 3 phases power distribution network that involves 33kV to 11kV (credit: www.iitk.ac.in).

Our team of engineers work with power transformers on a daily basis, providing services such as cable jointing, transformer testing, fault finding, maintenance, installation, and repairs.

However, over the last few years, we have performed transformer maintenance with 33kV systems that convert the power to 11kV. This power can then be safely distributed to power a town near the transformer.

Below is one of the 33kV to 11kV transformers to which our team has added our very own capacitors to improve the transformer’s power factor correction.
