Line Frequency Variations

Line frequency variations
Frequency variations are changes in frequency above or below the nominal
frequency (60Hz in North America, 50Hz in Europe, for example). If the
frequency drops below the minimum threshold a low frequency event will be
recorded; if it exceeds the maximum threshold a high frequency event will be
recorded.
