Due to Corona Effect & Proximity Effect

Answer / mohamed

The system is supplying only to inductive loads.So the power
factor is low.Current increases in the system.remember
formula p=v*i and CU.LOSS The system is designed for certain
load demand and if the demand increases the the system could
not be able to supply the load.Increased current tends to
decrease the voltage to maintain power.So automatically
voltage drops in 3Ph system

Answer / zia abbas

due to low powe factor harmonic losses copper and iron
losses making the causes of voltage drop
