Disadvantages of Low Power Factor

Lower power factor on a line means that higher current is flowing through it, so for low/poor power factor:
1) Large line losses (Copper Losses)
2) Large kVA rating and size of electrical equipments need
3) Greater Conductor Size and economic cost
4) Poor voltage Regulation and large voltage drop
5) Low efficiency
6) Penalty from Electric Power Supply Company on low power factor

You can say another format, when someone ask the question-
In low or poor power factor, current will be increased, so, to transmit this high current. So we need the larger size of conductor and structure. Also, the cost of large size of conductor and structure will be increased.
