Transients in Synchronous Machines with Balanced Capacitive Loads

An analysis of the transient voltages and currents that occur when a balanced capacitance load is connected to a salient-pole alternator is presented. The 2-phase co-ordinate equations of Clarke, describing the ideal machine, are solved by means of the Laplace transform. Armature resistance and field saturation are neglected. Expressions result, giving amplitudes and frequencies of components of the transients.
