Description
Summary:The investigation of this study is concerned with the effects of single-phase induction motors in the electrical power system when a fault occurs. The study is involved with both experimental and analytical investigations. Single-phase induction motors do contribute during short circuits. The most important quantity is the instantaneous peak current after the short circuit and the time constants. This work describes the behaviour of single-phase induction motors connected in the electrical power system. The theoretical and the experimental tests confirm that single-phase induction motors do contribute in short-circuit currents. The theoretical and the experimental results show that AC series commutator machines do not contribute in short-circuit currents.
