Abstract

Covers a method for calculation of short-circuit currents in d.c. auxiliary systems in power plants and substations. Deals only with rectifiers in three-phase a.c. bridge connection. Provides a generally applicable method of calculation which produces results of sufficient accuracy on the conservative side.
