A Guide to the Application of Capacitors without Induction Motor Self-Excitation

This paper develops a straightforward method for determining the maximum amount of capacitance which can be connected in parallel with an induction motor and static load combination without danger of self-excitation. Special consideration is given to the effect of the static load. Graphical results are presented which can be readily applied to a wide range of induction motor size and static load combinations. The effect of the static load is to increase the amount of capacitance which can be used safely without induction motor self-excitation.
