What is the use of Transformer in roadside?
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 corresponding
decrease or increase of current in the circuit. If the transformer converters
an alternating current with high voltage, it is called step-up transformer. If the
transformer converts alternating current with high voltage into an alternating
current with low voltage, then it is called step-down transformer.
How is Energy losses occurred 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 as 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 as core loss.
