Email Alerts with Canvass
Canvass is a feature-rich data analysis web application and database developed by Power Monitors, Inc. to provide a complete RMS voltage picture to users via any device equipped with an…
Understanding IEEE Flicker, IFL, Pst, Plt
This white paper covers and explains three of IEEE's most common Flicker definitions: IFL, Pst and Plt. The GE Flicker Curve and how other measurements standards compare to the GE…
New Additions to the Canvass Interface
Power Monitors, Inc. Canvass, our web based electrical data analysis software, has recently been upgraded with many new features. New features include: A new menu window, a Canvass message inbox,…
Measuring Frequency with PMI Recorders
Line frequency is the most tightly controlled parameter in the electrical distribution system. Since almost all generation in a region is connected essentially in parallel, the frequency is inherently synchronized…
Monitoring a 2½ Element Wye
A 2½ Element WYE Configuration uses 3 current phases and 2 voltage phases to calculate what is on the third voltage phase in order to measure the total power on…
NMS Security
NMS (or Network Management Software) is an application designed and developed by PMI for managing and configuring Boomerang voltage monitors. This white paper focuses on the different layers of security…
THD-F vs THD-R
There are two typical definitions used when dealing with Total Harmonic Distortion. The two types of Total Harmonic Distortion are THD-F and THD-R. They both are figures of merit used…
Faulty Capacitor Bank Switching
Abstract Troubleshooting electrical power and equipment failure incidents is not unlike a crime scene investigation that establishes not only collateral damage, but also attempts to determine, using investigative techniques and…
Understanding Socket Recorder Form Factors
There are a large combination of meter forms for single and poly-phase socket recorders. Understanding the different form factors can be challenging when choosing a meter base specific socket recorder.…
Optimizing Waveform Capture Triggering
Waveform capture is the highest resolution data available for PQ analysis and is often crucial in solving tricky issues. Successfully triggering on the waveform doesn't have to be tricky, though.…
Mixed Graphs in ProVision: Advanced Features
The mixed graph feature in ProVision is useful for combining traces from multiple files or the same file when the traces would not be graphed together. Mixed graphs are available…
