Mention various (any four) energy losses in a transformer.

  • 1

Here are four common energy losses in a transformer:
(i) Core Loss (Iron Loss):
This occurs in the transformer core due to hysteresis and eddy currents when it is subjected to alternating magnetic fields.
(ii) Copper Loss (Winding Resistance Loss):
This happens due to the resistance of the windings, causing heat loss when current flows through the transformer coils.
(iii) Leakage Flux Loss:
Some magnetic flux does not link perfectly between the primary and secondary windings, resulting in energy loss.
(iv) Stray Losses:
These are caused by stray magnetic fields that induce currents in nearby conductive materials, such as the transformer tank or other structural parts.

  1. Four common energy losses in a transformer are:

    Core Losses (Hysteresis and Eddy Current Losses): These occur in the transformer core due to the alternating magnetic flux, causing energy dissipation through heat.
    Copper Losses: These losses arise from the resistance in the windings of the transformer, where current flow generates heat.
    Leakage Flux Losses: Incomplete magnetic flux linkage between the primary and secondary windings leads to energy loss.
    Dielectric Losses: Energy is lost due to the imperfect insulation material in the transformer.
