Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to the other. This can be a pronounced advantage in power system analysis. Conversion of per-unit quantities to volts, ohms, or amperes requires a knowledge of the base that the per-unit quantities were referenced to. The per-unit system is used in\u00a0power flow,\u00a0short circuit\u00a0evaluation,\u00a0motor starting\u00a0studies etc. The course Per-unit Systems Applied to Power System introduced and developed the p.u. systems applied to concepts and themes of power systems field to engineering students.<\/p>\n<p>Objectives:<\/p>\n<p>1.
