Analyzing Voltage Sags with RMS CaptureAnalyzing Voltage Sags with RMS Capture_02

Learn how powerful ProVision's RMS Capture tool is and why it is ideal for analyzing voltage sags.


This white paper covers the topic of voltage sags and a sometimes under-used graphing feature in Provision called the RMS Capture graph.


The RMS Capture graph can be very revealing when evaluating and analyzing voltage sags.


The RMS Capture allows a user to produce a graph with waveform-level detail without having the scaling problems that occur when using raw sine waves for RMS readings.


When there is a measurement need for RMS information, such as analyzing voltage sags, an interval graph does not provide enough detail, and a raw waveform capture plot has an overwhelming amount of detail, along with scaling issues when viewing peak-to-peak sine waves.


Here the RMS capture graph may be the best overall view.
