This literature study provides a brief description of the history associated with the term ferroresonance. In addition, the underlying physical cause of ferroresonance is described.
The generation mechanism is presented with a simple example that can be reproduced by means of a voltage source, a capacitor and a small air-insulated single-phase transformer. General criteria of the emergence of ferroresonance are also presented. Some specific situations, where one should be aware of regarding possible ferroresonance, are listed.
