High voltage power supplies allow moving of electricity over long distance without extra power losses that can happen due to electrical conductors.
Benefits of high voltage power supplies are –
Reduced Power Loss
The long electrical lines across the roads are made from copper / aluminium and every current transmission is resulting in power loss. So, the amount of power loss during every transmission is relative to the current flowing through it. If there is less voltage used then the power loss will be greater and if high voltage power supply is used then power loss will be less. Hence, power loss is reduced if there is a high voltage power supply.
The cost of installing cables through which high voltage power supply will be passed is lesser than the cables required passing lower voltage power supply. This is because lower voltage supply requires cables which are substantially bigger than the high voltage supply. Transporting the high voltage power in lower currents helps reducing costs.
If you have reduced power loss and reduced costs, definitely the efficiency is improved of high voltage power supply. There will be less spending on equipments required and that money can be used for expansion, improved infrastructure and research and development. So, in turn efficiency in long term is surely improved.
The future of high-voltage transmission
Lot of scope of more usage of high voltage power supply as it has lot of benefits. There are plans, exciting projects underway to increase more capacity of the power and more people can benefit from this transmission.
The benefit of high-voltage power supply is clear and visible and is now widely used by all. It is now an integral part of our day-to-day life.
