What would be the ratio of a Delta-Wye tranformer having
48000 volts phase to phase on the primary and 4160 volts
phase to phase on the secondary?
Answer Posted / ipit
48000/(4160/sqrt(3)) = 48000/2401.77 = 19.98

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
