disorder

It is used synonymously with abnormal oscillation. In electrical and electronic circuits, this refers to a phenomenon where oscillation unexpectedly occurs at a specific frequency due to design flaws or wiring defects, disrupting functionality. In amplifier circuits, it can occur when part of the output feeds back into the input and is repeatedly amplified. Accurate design and wiring are essential to prevent abnormal oscillation. As a countermeasure when it has already occurred, changing the CL value of the component is one method.
In a separate usage distinct from abnormal oscillation, the term also refers to a phenomenon that occurs during parallel operation of generators, where the rotor vibrates before and after the synchronous speed due to sudden changes in load or driving torque. If generator instability increases, it deviates significantly from the synchronous speed and stops due to loss of synchronization.
