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…
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…
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…
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…
PQ Recording Templates
This whitepaper describes the use and customization of PQ recording templates in PQ Canvass, iPowerPad, and in the ProVision software. PMI recording devices can be initialized with many different configurable…
Wireless Power Quality
The time and cost of deploying PQ instrumentation only to return later in order to retrieve it (without the guarantee that the PQ anomaly has occurred) is often times exorbitant.…
Using Cycle Stripcharts
Stripchart recording is an important tool for analyzing complex data. It provides a visual means to easily digest extensive quantities of recorded information over long time periods. In most cases,…
Power Quality Recorder Setup Basics (Part 2)
This whitepaper is a continuation of WP241 (Recorder Setup Basics). In part one the details and relative memory consumption of interval recording was discussed along with the associated controls for…
Recording Interharmonics with the Revolution
Interharmonics are on the rise because of large non-linear loads and sources being introduced to the distribution network, in particular large Variable Frequency Drives (VFDs) and inverters for distributed generation.…
Cell, WiFi, and More with the New Cell Guardian Meter Socket Recorder
PMI has just introduced a major redesign of the Guardian meter socket power quality analyzer. This white paper will focus specifically on the new Cell Guardian recorder and cover the…
Configuring Alerts with a Guardian in PQ Canvass
PQ Canvass is Power Monitors Inc.’s newest iteration of web-based power quality analysis software. It builds on the foundation established by Canvass and adds many new features, including variable-interval stripcharts;…
