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…
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…
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…
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,…
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…
Measuring Demand with ProVision
Most of PMI's power quality analyzers have the ability to measure Power. Depending on the model and options, it is often possible to measure to kW, kWh, kVAR, and VA.…
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…
Identifying Loose Neutrals
This white paper describes what a loose neutral is, what effects it can have on electrical equipment, its causes, and some ways to easily detect if a loose neutral is…
ProVision PQDIF Export
ProVision's native data file format is designed for efficient storage and access of all PQ data from the full line of PMI recorders. However, ProVision can also export certain data…
Flex CT Overview
This white paper describes what a Flex CT is, how it works, and a brief history on its development. Details are given on how to use the Flex CT to…
