Voltage drop especially in 3 phase system is due to low
power factor.Low power factor leads to increase in I2r
losses which in turn increses the regulation.As regulation
increases voltage drop occurs which directly effects the
efficiency of generation and increase in stress of
transmission line.Thats why KEB people who are responsible
for maintaining required voltage put fine if we maintain
low power factor.Corona and skin effect are negligeble .
