Spot Sags, Loose Neutrals, THD, and More with Custom Graphs

Category: ProVision, PMI Products

Understand how to spot voltage sags, loose neutrals, THD and much more with PMI's Custom Graph wizard.

 

Finding voltage sags, loose neutrals, THD correlations, and other PQ problems in a mountain of recorded PQ data can be time-consuming at best.

 

The ProVision Custom Graph Wizard lets you go beyond the built-in graphs to create templates fine-tuned for teasing out correlations between current spikes and voltage sags, loose neutral voltage swings, voltage THD and load current, and any other combination of data types.

 

One example detailed in this paper is that of voltage sag issues in which only the minimum sag voltage is [often] of interest in order to determine whether the load current is the cause of the sag, and the maximum current is used.

 

If the voltage sags while the current spikes, the load current is likely the cause of the sag. If the current drops in step with the voltage, it’s likely not the cause of the sag...
