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…
Computing Event Duration With Interval Data
Although interval (stripchart) data can show cycle max and min readings, it's not normally used to get the duration of an event like a sag – waveform capture, event capture,…
Conservation Voltage Reduction with the Boomerang
Conservation Voltage Reduction (CVR) is a method for lowering peak energy demand by lowering the average system voltage during the peak periods. The Boomerang is designed to work with any…
Harmonics from Periodic Waveform Capture
Harmonics are usually recorded as interval (stripchart) data in PMI recorders. Each desired harmonic is recorded as a min/ave/max stripchart trace, for each desired voltage and current channel. Although this…
Network Configuration for Revolution and Vision
PMI's Revolution and Vision power quality recorders come equipped with Ethernet/networking capabilities which are easily configurable to allow quick connection and communication over a company's network. This white paper will…
