why three-phase? - Fronius International
... Electricity is connected at 230, 240 volts (single-phase), 400 or 415 volts (three-phase). Single-phase enters the home via two wires: active and neutral. Three-phase has four wires: three actives (called phases) and one neutral, which is earthed at the switchboard. Three-phase electric power is mor ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
