Estimating THD with Power Factor Histograms
In the previous whitepaper Estimating THD with PF and DPF, a technique for estimating THD was shown given power factor and displacement power factor stripchart data. In many case, there's…
Analyzing Voltage Sags with RMS Capture
This white paper covers the topic of voltage sags and a sometimes under-used graphing feature in Provision called the RMS Capture graph. The RMS Capture graph can be very revealing…
Provisioning Boomerangs with a cellular data plan for Canvass and/or SCADA Systems
The Boomerang is one of the newest power quality measurement offerings by PMI. Capable of measuring voltage, current and real power, the Boomerang comes in multiple different measurement configurations and…
Interharmonic Recording and Data Analysis
Interharmonics are one of the most complex power quality quantities to measure and analyze. The concepts are advanced, the terminology is confusing, the raw data is voluminous, and the interpretation…
Case Study: Electric Tankless Water Heaters and Power Quality
In this case study, an investor-owned utility responded to a residential customer complaint. The root cause was a newly installed electric tankless water heater, requiring a transformer upgrade beyond the…
Voltage Sags and Power Quality
This white paper describes what voltage sag is, some of the most common causes of voltage sag, the adverse effects voltage sags have on end users, and how to monitor…
Using the Flicker Curve Worksheet
In this whitepaper we will discuss how to use the PMI Flicker Calculator worksheet to visualize and assist in customizing flicker settings in ProVision. This worksheet was briefly mentioned in…
Canvass and Cybersecurity
Canvass is PMI's web-enabled distribution system monitoring and analysis platform. Deploying Canvass as a web application provides a wide array of benefits: one installation base (no need to push updates…
Using Mixed Graphs for Distributed Generation Analysis
Analysis of recordings of distributed generation (e.g. solar, wind, etc.) systems present new challenges for utilities. Distributed generation analysis usually involves looking at voltage and power, voltage and voltage THD,…
Using the Revolution Mounting Bracket
The PMI mounting bracket provides a variety of methods to temporarily or permanently attach a Revolution or 3-phase Boomerang to a metal enclosure, mounting plate, or many other points. Internal…
Electric Tankless Water Heaters and Power Quality
In this whitepaper the basics of electric tankless water heaters (TWHs) are presented, along with their potential impact on voltage quality. Real-world graphs are discussed to illustrate the significant impact…
