Power Quality in Traffic Signal Cabinets
The first electric traffic signals were installed over 100 years ago but now are a ubiquitous aspect of modern life. Today's intersections are far more complex, with a cabinet of…
TDD and IEEE 519:2014
IEEE standard 519 was first released in 1982 and was then updated in 1992 and 2014. It defines limits on Total Harmonic Distortion (THD) as well as Total Demand Distortion…
Viewing PQCanvass Boomerang Data in ProVision
Boomerangs smart grid sensors transmit RMS voltage, current, and power data to cloud-based Canvass and PQCanvass systems. Canvass/PQCanvass provide web-based data analysis tools, email/SMS notifications, and long term data storage…
Understanding Crest Factor
Crest factor is an often neglected power compatibility measurement, but can be very important in certain applications. This white paper presents the definition of crest factor and the method for…
RMS Measurements and Harmonic Analysis
The RMS value is used to quantify the overall "size" of a waveform with a single number. By extension, harmonic amplitudes can be used to describe a complex waveform with…
Measuring and Analyzing Voltage Regulation
Voltage Regulation Basics Utilities are generally required to ensure the delivered steady-state voltage is within the limits specified in ANSI C84.1. Persistent under- or over-voltage can result in customer complaints…
Holdoff and Aggregation with Canvass Alerts
Email/SMS alerting from Canvass is a powerful feature providing real-time notification about distribution events and equipment problems in the field. Some notifications require immediate truck rolls, and others are less…
Transferring ProVision Recordings to PQCanvass
We've added a major enhancement to ProVision - the ability to sync recordings with PQ Canvass, PMI's cloud-based PQ data analysis system. The implications of this are profound because you…
DNP3 Point Map 2.0 Update
The Boomerang family of cell-connected distribution monitors continues to expand. This expansion includes updated hardware, added features and new capabilities. These changes along with customer input have driven the need…
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…
