Explain the electrical characteristics of transformer.
Transformer electrical characteristics:
Area of primary and secondary conductors, Apri and Asec:
Winding loss Pw:
Flux density and core loss:
Short circuit current:
No load current:
Effect of a rise in temperature on transformer:
High-efficiency transformer has a low rise in temperature while low-efficiency transformer has high rise in temperature. Temperature rise affects the transformer span. The rise in temperature may breakdown insulation which may cause failure of the transformer.
