In a power distribution system having long radial cable fed lightly loaded transformers provided with fuse protection at the tap off point, ferroresonance is a common phenomenon. Based on the recent studies carried out on a Malaysian utility's distribution network, the paper shows that to diagnose existence of ferroresonance, it is essential to check presence of overvoltages as well as the presence of multiplicity in periodicity through some kind of frequency spectrum analysis. Few cases with their configuration and performance as obtained through EMTDC simulation are also presented.
