Hesteresis and its influence on the creation of the ferroresonance

The effort to decrease the power dissipation in the energetic system stemming from increasing ecological and economical requirements is the reason of the growing frequency of occurrence of various incidental phenomena. It is important to consider the system as a whole, so it is necessary to take into account the fact that lowering the power dissipation will lead to absorption in the system. However, that results in increasing and lengthening the system´s response to any change, and therefore also to the character of transient phenomena. In the electric power system these are usually a short-term increase or decrease in voltage. It can also happen that as a result of a change in the system, the voltage will increase permanently, which might have a destructive effect on most electrical appliances.
