Abstract
This paper investigates the dynamic behaviour of tap changing operations in tap change under load (TCUL) transformers. Interactions among multiple TCUL controls cause oscillatory behaviour in tap changing actions, which unnecessarily increases tap operations before they reach equilibrium. Sufficient conditions for stability are derived and features of the phenomena are examined through theoretical analysis as well as through numerical simulation
