If u connect the data motor in star the power of this motor will be deceased 1/3 as like u connect a 15,HP motor in star it will be work 5hp motor

some practicle study shows that the reactive power at the receiving end is not equal to the reactive power at the sending end.But according to theory the reactive power is exchanged by different parts of the network – capacitors and reactors permanently, but is never consumed or produced. Then Where that reacrtive power loss occuring?is there any formula to calculate reactive power loss?
