Answer Posted / ma.amulraaj,b.e. mba.,
The previous answer is wrong.Because irrespective of equipment,we have to manufacture any equipment economically.
If we provide the HV winding Near to the core,Suppose the HV voltage is 11000V.We have to provide the insulation between core and HV coil is 11000 V.Then in between HV and LV winding agin we have to provide insulation 11000 V.Here The insulation cost is very high.
In other way ,if we provide LV winding near by core,the LV voltage is 415V,we have to provide insulation for 415 V between core and LV winding only.So cost of insulation is considerabily reduced.
That is why HV winding is not placed near to core.

We have received supplies of the ordered material. payments against the supplies also released. Where ST paid 4% against form C. Meanwhile it has been observed that 25% of material supplied was defective. Please suggest whether the issuance of C form from our side would be stopped till settlement of liabilities.
ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
