Frequency events are variations in frequency above or below the nominal
frequency (for example, 60Hz in North America and 50Hz in Europe).
Variations in frequency are typically a few cycles and can be from seconds to
minutes in duration.

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.

The factory default nominal frequency is 60Hz for 110V models and 50Hz for
220V models. However, PowerWatch can be user configured to record at
50Hz and 60Hz for either 110V or 240V models.

Loss of Synchronization Event

Loss of Synchronization Event

Excessive harmonics or noise on a power line may cause severly distorted
voltage waveforms. While not common, these distorted waveforms could
result in "extra" zero crossings on the AC line.
