What is IEC 60909 Short Circuit Calculation Guide about?

The document discusses the methodology for calculating short circuit currents in electrical power systems according to IEC 60909. There are six main steps: 1) construct a system model and collect equipment parameters, 2) calculate equipment short circuit impedances, 3) refer impedances to a reference voltage, 4) determine a Thevenin equivalent circuit at the fault location, 5) calculate balanced three-phase short circuit currents, and 6) calculate single-phase to earth short circuit currents. The goal is to
