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…
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.…
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…
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…
Mixed Graphs in ProVision
ProVision offers a wide variety of graph types, ranging from voltage and current to histograms and profiles, and the ability to open multiple independent graphs, each containing data from different…
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.…
Histograms in ProVision
ProVision software includes the ability to analyze power quality data with several different graph types. This paper will focus on ProVision's histogram graphs. ProVision includes ten different types of histogram…
Tabs and Windows in ProVision
Most software products have a graphical user interface (GUI) that allows the user to interact with the program, and ProVision is no exception. Some of these interfaces can be quite…
RMS Capture Graph in ProVision
A little-known graph in ProVision, the RMS Waveform Capture graph, can actually be one of the most illuminating. In cases where interval graphs don't have enough detail, and raw waveform…
