POWER QUALITY BASICS: FERRORESONANCE

Wednesday, February 29, 2012

Ferroresonance is usually described as an irregular and chaotic type of resonance. This phenomenon occurs because of the nonlinear characteristic of iron-core (saturable) inductors - ferromagnetic material such as a transformer. Ferroresonance is often times associated with unwanted and destructive overvoltages, but has found some helpful applications in Constant Voltage Transformers, which can mitigate power quality problems like voltage sags.
