How to calculate the lighting load & power load requirement by knowing area of building/room. Is there any thumb rule?
3 17980Electricty is generated at around 16kV, then step up to 220kV for transmission then steped down to power transformers then DTs and then through the LT n/w it reaches the consumer end. At the consumer end 230V supply is required. So, why is electricity not generated directly at 230V and transmitted?
