why select the 3 phase power supply system in electrical system.
Answer Posted / raghavendra
basically power is required for each and every appliance we use like motors ,fans,ac,tv's,fridges etc.for each and every load there should be different type of supply . the three phase supply increases the efficiency of single phase supply by 50 percentage .but further increase in phase like six phase increases the efficiency by only 7 percent only and also leading to more complications on the generator side , and further increase in phases also leads to same case increasing the complexity on generator . so 3 phase supply includes 3 phase double circuit supply ,3 phased 3 circuit supply and so on........................
