Resistance depends on the size of the conductor and
length/phase..More the horse power less the resistance.To
calculate, you need to the length of wire per phase , the
sectional area and the resistivity of the conductor material.

Answer / o.p.arya

first of for we will check the motor current at the name
plate and then provide the constant dc voltage gradually to
phase winding of motor up to rated phase current and
measure the voltage & current both with very carefully.then
calculate it. as r=v/i it will be the standard resistance of
motor winding.
name plate current(line current)
phase current =------------------

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill. Q: Identify the appropriate solution you want to offer to Client?.Justify SCIENTIFICALLY and MATHEMATICALLY the principles behind the solution.
