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…
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…
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…
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…
Hidden Delta Voltage Unbalance
Voltage unbalance can cause severe heating in motors and large DC power converters. Although most voltage unbalance is caused by unequal loading among phases, shifts in voltage phase angle can…
Transient Capture vs. Waveform Capture
Most PMI recorders include waveform capture, and the Revolution optionally includes a high-speed microsecond-level transient capture system. Although PMI waveform capture and transient capture seem very similar on the surface,…
Voltage Swell from Recloser Operation
A recloser is most associated with brief voltage interruptions, possibly followed by an extended outage if a fault cannot be cleared. Upstream customers experience voltage sag during the reclose attempts,…
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…
Overcurrent Protection with Fused Leads
PMI offers a fused voltage lead kit for increased safety with the Revolution and Eagle power recorders. Although not required to meet UL safety standards with these recorders, the fused…
Browser Security and Performance with Canvass
Canvass is a powerful graphical web application for the viewing and analysis of voltage, current, and power data collected by PMI Boomerangs and Revolutions. Hosted at https://canvass.powermonitors.com, the application provides…
Getting Started with the Pole Mount Boomerang
This white paper will explain the process of installing and communicating with a Pole mount Boomerang voltage/current/power sensor (Figure 1). The pole mount option includes a rugged, weatherproof NEMA 4X…
