What is the use of Transformer on the roadside?
A transformer is a stationary device used to transform
electrical power from one circuit to another without changing its frequency. The
applied alternating voltage is either increased or decreased with a corresponding
decrease or increase of current in the circuit. If the transformer converts
an alternating current with high voltage, it is called a step-up transformer. If the
transformer converts an alternating current with high voltage into an alternating
current with low voltage, then it is called a step-down transformer.
How are Energy losses occurring in a transformer?
When an electric current flows through them, some amount of
energy is dissipated due to joule heating. This energy loss is called a copper
loss. Energy loss due to the flux leakage is minimized by winding coils one
over the other. Hysteresis loss and eddy current loss are called core loss.
