Frequently Asked Questions.

How do distribution transformers work?

A distribution transformer comprises zero moving parts, making its working a fairly simple process.

The transformer’s main body rooms two or more coils of insulating wires woven around a steel core. On the introduction of voltage to the Primary /Input coil, the core starts magnetizing. As a result of magnetization, the voltage gets transferred to the Secondary/Output coil. The turn ratio of both coils determines the change in levels of voltage and final distribution.

Which transformer is used in distribution?

According to distribution transformer manufacturers, a step-down transformer is an ideal option for distribution purposes. Why? Because in the distribution network you need to change the high voltage low current from power generation plants/substations to a low voltage high current supply feasible for the usage by end consumers.
