Earthed system

WebIts amplitude is determined by the system earthing conditions and its duration by the fault- clearance time. If the earth-fault factor, (k) = Utov/Uca, is 1.4 or less, the system is considered to be effectively earthed. Generally, this implies a solid connection of the neutral to the earth grid. WebDistribution of electrical energy to consumers in a town or village is carried out by the three-phase, four-wire system. In this country, the secondary windings of a three-phase star-connected transformer usually have a line voltage output of 415 V and so the voltage between any line and the neutral conductor is 240 V.
