Summarise the reasons for a three phase supply network A three phase network is a commonly used method to alternate current electric power into generation transmission and distribution Worldwide Power Grids use the system to transfer power The main reasons the three phase network was put in place is due to the fact that it has a longer lifespan than that of a one phase network A three phase network will produce 3x the power of that of a single phase network Also with the three phase you get 3 wires instead of the usual 2 wires Another reason three phase networks are used is the fact they can withstand more pressure and force For example if a turbine has a single one phase generator the probability of it being shaken to the point of disconnection due to the vibrations and torque varieties is quite high supply 2018 However a single three phase generator could handle this without any stress or problems Constant power is one of the three phase network s key features
