In those seconds, inertia provides frequency stability and enables the power system to maintain its operational frequency level — 60 Hz per second in the United States, and 50 Hz per second in Europe and much of Asia. Without inertia — either due to production variations or load shedding — sudden changes in frequency will become faster and larger, meaning the residual time will be much reduced and the normal range of variation will be increased largely. PROMOTED Grid operators can't fix a frequency problem in an existing system without employing ancillary services. If frequent variation isn't corrected, things will fall apart. In this situation the electrical system fails, possibly with a cascading effect. In the
