disorder

Used synonymously with "abnormal oscillation." In electrical and electronic circuits, this refers to a phenomenon where unintended oscillation occurs at a specific frequency due to design flaws or wiring issues, hindering proper functionality. In amplification circuits, it can occur when part of the output feeds back into the input and repeats amplification. To prevent abnormal oscillation, accurate design and wiring are crucial. As a countermeasure when it has already occurred, changing the element's CL value can be effective.
In a separate usage distinct from abnormal oscillation, this term also refers to a phenomenon during parallel operation of generators where the rotor vibrates around the synchronous speed due to sudden changes in load or driving torque. If the generator's instability increases, it deviates significantly from the synchronous speed and stops due to loss of synchronism.
