Waveform Examples for Frequency Deviation Events

Frequency Deviation Event

A Frequency Deviation Event will be triggered (and a waveform consequently captured) when the frequency of the RMS value of the voltage waveforms, normally either 50Hz or 60Hz, exceeds the triggering threshold. Most systems will operate fine with a couple of Hertz difference (48 to 52Hz, and 58 to 62Hz, for example), but a larger frequency shift could cause clocking or triggering problems in electronic systems that rely on voltage waveform frequency stability.

This type of waveform is very difficult to see graphically, and does not occur often.

How Do I Adjust The Trigger Thresholds?

To adjust the set-points of the event triggers, please refer to the Users Manual, section 3.6.

How Do I Eliminate These Kinds of Events?

To reduce or eliminate these kinds of power events, you may need to increase the level of your power conditioning to a Voltage Regulator or a UPS. For more information, visit our Additional Power Conditioning web-pages.
