Summary

Most coltage collapses turn out to have a critical time scale of the order of a few minutes. This is just slow enough to be within the scope of what an operator can handle, but leaves absolutely no time to waste before appropriate action should be taken. Hence the world-wide interest in reliable early detection of voltage instability risks and accurate indication of the endangered areas.
