Answer Posted / majid dadjoo
with reactive power corection you can decrease reactive
power on line . it means that by reducing reactive
power ,same active power can transmit by a line with lower
current than previous.

Why does curving the pole faces in a dc machine contributes to a smoother dc output voltage from it?
When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
