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…
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.…
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…
Analyzing K Factor
K Factor is a measurement of current harmonic distortion that is used to de-rate transformers for harmonics. This white paper will discuss how K Factor is calculated, what its uses…
Boomerang Burst Mode Operation
PMI's latest software and hardware solutions (Canvass and the Boomerang) provide a tremendous new platform for voltage monitoring. As long as Boomerang monitors are powered up they are constantly sending…
Exporting Data from ProVision
The majority of commercially-available software products typically work with files that have a special extension. These extensions are indicative of a proprietary or unique file format custom-tailored to work with…
