Explain why the Voltage drop will happen in 3 Phase line?

Answer Posted / 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

1) why a dg set shows variation of power factor and load when synchronised with other dgs? 2)Why the load sharing is not become equal in all dgs?. 3)When a dg set will not run on auto start?
