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…
Identifying Sources of Voltage Sag
In this white paper methods for determining sources of voltage sag are discussed, as well as some example files that have identifiable sources of voltage sag. When placing a recorder…
DNP3 UDP vs TCP Configuration
The DNP3 (Distributed Network Protocol v3) is a communication protocol designed for interaction with control (such as SCADA – Supervisory Control And Data Acquisition) systems. Power Monitors has recently introduced…
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…
Changes Presented in ProVision 1.60
The communication software provided by Power Monitors has received several substantial updates since its inception. The most recent major version released is ProVision 1.60. This whitepaper serves as a summation…
