Over Fluxing in Transformer: Causes, Effects, and Permissible Flux Limits
Overfluxing in transformer is a critical condition that occurs when the voltage-to-frequency ratio (V/f) exceeds its designed limit, leading to an abnormal rise in core
Transformer
Transformer is the static piece of equipment used for step up and step down the voltage for economic transmission and utilization of electrical power.
In this section we are adding all the technical articles related to transformer like step up transformer, step down transformer, ideal transformer, efficiency and losses, regulation, percentage impedance.
