Short circuits are relatively common, but they can be dangerous and a warning sign of a possible electrical hazard, so it's important to know what short circuits are and how to prevent them in ...

Any short-circuit conditions which might possibly occur in practice can be produced in their testing room. The generators are driven by 5,500 volt motors connected with the public supply mains.

During an accidental short circuit, enormous currents may be generated, and if the circuit be not broken by suitable switchgear, great damage may be done to very expensive cables and generators.
