Case Study: Spotting Pump Failure with a Boomerang and Canvass
In September of 2017 a homeowner discovered that his well was not delivering water. The suspicion was that the pump itself was in some way failing – perhaps the motor…
Waveform Capture with Transient Capture Overlays
PMI Revolution recorders can record waveform captures and, with the transient capture option, high-speed microsecond-level transient captures. Transient captures have a much higher sampling rate than waveform captures but have…
Managing Outages with Canvass and PQ Canvass
Responding to outage management is of the utmost importance to any utility, but you can't respond to a voltage interruption that you don't know about. Deploying an Outage Management System…
Understanding Harmonic Power
Harmonic power is a complex and often misunderstood topic. This leads to misinterpretations, including using a harmonic power analysis when the measurements aren't physically meaningful. An overview of harmonic power…
Getting Started with Harmonics
Harmonic distortion has become an increasingly important subject for large power consumers. Non-linear loads continue to be adopted into customer systems, which often are the root cause of power quality…
Live PQ Waveforms in a Web Browser
PQ Canvass is the next generation of online power quality analysis tools provided by PMI. This new cloud service offers enhanced graphing, a full suite of PQ analysis tools, recording-based…
Separating Voltage Sags from Steady State Voltage Readings
Ensuring that service voltage is within ANSI limits is a basic but important step in delivering power. Sophisticated programs such as Conservation Voltage Reduction (CVR) and volt/VAR optimization require continuous…
Merging Recordings in ProVision
Many PQ investigations end with a follow-up recording to verify a problem has been corrected and to gather a baseline for any further issues. Analyzing the “before” and “after” recordings…
Quickly Creating PQ Reports
The ProVision Publication Wizard is a quick way to create finished documents from individual graphs and reports. Use the wizard to create publication templates for different PQ applications, and then…
Measuring Power
The Revolution is a powerful tool for measuring and recording power quality information. With ProVision, there are a wide variety of ways to display and analyze many different types of…
Advanced E-Mail Alerts in Canvass
One of the most popular, and useful, features in Canvass is the Distribution List, which allows any chosen alert or event, from any Canvass-enabled device, to be transmitted by email…
