can u solve(T/F)

hi,

we connect a load across transformer, will some one explain the procedure in sequence how transformer will start draw more current as load increases. please consider mutual linkage of flux also....

Dear Harjeeth sir

This is basics.

Ok I,ll give some information.

Normally when u increase the load,the Tfr will supply more current to load.The magnitude of current depends on %age of load.

In tfr,flux developed in the core will not depends on load.It is constant.Hence the core loss also constant.But depends on load current,copper loss will vary.If load current is more and more means, more copper loss,then more heat.It will damage the insulation

so we have to provide better cooling.If the cooling is better, u can load more.

For further information,please refer any standard book like Electrical machines by M.G.Say, electrical machines by B.L.Theraja

cheers
