Advanced Waveform Capture with ProVision
Waveform Capture data is often the most detailed information available in a PQ recording. Getting good data is not always easy, so it's important to glean all information possible from…
Views in ProVision
ProVision lets the user save a specific set and layout of graphs and reports in a View, which can easily be reused for any data file. The default View is…
New Graph Templates for Interharmonics
Analyzing interharmonic data is a complex process, due to the large amount of information recorded. ProVision 3D graphs help for quickly identifying specific interharmonics that merit a closer look, but…
Analyzing Voltage Sags with ProVision
This white paper provides an overview of how to find and analyze various aspects of voltage sags using ProVision and data captured using PMI's recorders. For a given dataset, where…
Easy to Use Harmonic Graphs in ProVision
Harmonic distortion is an increasingly common power quality problem, and one of the most complex to analyze. Going beyond the total harmonic distortion to assess each individual harmonic takes time,…
Migrating ProVision to a New Computer
Given the rate at which technology and computers are improving, sometimes it is necessary to phase out an existing system in favor of a newer one. However, if the previous…
New Graph Templates for Distributed Generation
The use of distributed generation (DG), e.g. photovoltaic and wind farm systems, presents new challenges to the electric network. Unpredictability and sudden changes in generated power results in changes in…
Exporting Harmonics with the ProVision Bulk Export Tool
Harmonic stripcharts can generate huge amounts of data. When using harmonic data outside of ProVision (for computing system-wide TDD, comparison with other data sources, etc.), a way is needed to…
Spot Sags, Loose Neutrals, THD, and More with Custom Graphs
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…
Net Metering in ProVision
ProVision offers a wide variety of reports and graphs for displaying various types of power quality data. One of these is the power consumption report. Newly added to this report…
In Place Updating with ProVision
ProVision, the power quality data analysis software provided by PMI, is constantly modified to meet the changing needs of engineers and technicians, and to ensure compatibility with other hardware and…
