Approaching Power Quality Monitoring Site-Work
Power quality (PQ) monitoring provides insightful information that can be used to detect industrial and residential power disturbances, and provide clues for mitigation and problem resolution. Having the proper power…
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…
Electric Vehicle Charging and Power Quality
Several months ago PMI purchased a Nissan Leaf all-electric vehicle. The Leaf has an approximate range of 90 miles which fits well with our day to day usage for local…
New Graph Templates for Flicker Analysis
Voltage flicker is one of the most visible and common residential complaints, yet one of the most challenging to quantify and address. The IEEE 1453 flicker standard defines some important,…
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…
Voltage Optimization with the Boomerang and Canvass
The Boomerang voltage sensor and Canvass software are essential pieces in a successful Voltage Optimization system, providing the long-term reporting needed for verification and system tuning, while also providing real-time…
Evolution of Power Quality Recording
Power quality analysis is a rapidly changing field, and is intrinsically linked to advances in digital technology. From its humble beginnings as analogue recorders that wrote a single voltage directly…
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…
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…
Predictive Power Monitoring
Power Quality Monitoring data can be used to detect and identify potential problems either before equipment begins to fail or before it fails completely. Symptoms recorded by PQ monitors can…
Minimizing Data Usage with DNP3
The DNP3 protocol was originally developed back in the day when a wired connection to devices was the norm. The protocol was designed to be robust and very reliable but…
