Many sags are caused by a singlelinetoground fault (SLGF). Double and threephase symmetrical faults are infrequent, occurring less than 20% of the time. Asymmetrical faults cause voltage unbalance and phase shift. A large motor starting within the plant can also cause voltage sags. However, these usually have a balanced effect on all three ...

Excessive wear profiles due to long campaigns can cause localized overloads at the barrel ends which favour the initial crack. Continued rolling propagates the crack, exiting at the freeboard and failure then occurs. This is a mill fault. Damage of steel roll due to hydrogen.
