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…
Alert Level Programming and Analysis
The proliferation of cellular networks has allowed for quick access to information when it is needed. This quick access to information is available from all of PMI's cell enabled products…
Blondel’s Theorem: One Less Connection for Three-Phase Power
Polyphase power networks are among the most common networks for power transmission. They offer key advantages over single-phase networks. A polyphase system allows the same power to be distributed with…
New ProVision Release for Handling Large PQ Recordings
With the introduction of the cell Guardian, 1 GB of memory in a PQ recorder is increasingly common. Although the resulting large files can provide a wealth of data, they…
Analyzing Voltage Sags with Event Change
Identifying the sources for voltage sags can be a somewhat complicated task. Graphs such as waveform capture can obscure the essentials with an RMS-based voltage sag. PMI provides a triggered…
CBEMA-ITIC Analysis with Stripcharts
The ITIC curve (formerly CBEMA) is a performance-oriented standard for electronic equipment manufacturers. The standard gives a method for classifying and plotting voltage events on a specially constructed graph that…
Recording for NEC 220 Compliance
Utility customers who are expanding operations or adding load must comply with National Electric Code Article 220 to determine if any electrical upgrades are needed. Many customers will ask the…
Zero Sequence Harmonics
In this whitepaper, I will discuss zero sequence harmonics: what they are, how they are created, and what issues they present to distribution systems and power quality. Zero sequence harmonics…
Sharing Cloud Based Data
Canvass provides a cloud-based system for gathering, storing, and analyzing voltage, current, and power data from Boomerangs and Revolutions. In large deployments, with hundreds or thousands of devices, it's more…
THD Waveform Capture Triggering
The simplest waveform capture triggering is based on RMS voltage or current changes. While sufficient for voltage sags, recloser operations, etc., more complex events such as cap bank switches, narrow…
