Networking the Ethernet Boomerang
PMI's Ethernet Boomerang monitors can be powered over Ethernet for real-time voltage, current, and power monitoring. The Ethernet Boomerang allows quick connection and communication over a company's network, without incurring…
New Graph Templates for Distributed Generation
The use of distributed generation (DG), e.g. photovoltaic and wind farm systems, presents new challenges to the electric network. Unpredictability and sudden changes in generated power results in changes in…
Detecting Recloser Events with Boomerang Monitors
Boomerangs provide advanced triggering mechanisms that can be used to detect and send an alert for Recloser events. A "Voltage Low Low" event will be used to trigger an alert,…
Finding the Source of Harmonic Problems
This white paper explores the feasibility of using a common measurement point between the source and load to determine the source of harmonics using only harmonic phase angle. Finding the…
Recording Harmonics
There are three primary recording types for harmonics in PMI recorders: stripcharts, daily profiles, and waveform capture harmonic analysis. Each of these has specific pros and cons, and setup considerations…
Using Standard Deviation To Get More from Daily Profiles
The Canvass power quality portal provides the user many different tools for analyzing voltage, current and power over considerable periods of time. One such tool is the Daily Profile Graph,…
Exporting Harmonics with the ProVision Bulk Export Tool
Harmonic stripcharts can generate huge amounts of data. When using harmonic data outside of ProVision (for computing system-wide TDD, comparison with other data sources, etc.), a way is needed to…
Spot Sags, Loose Neutrals, THD, and More with Custom Graphs
Finding voltage sags, loose neutrals, THD correlations, and other PQ problems in a mountain of recorded PQ data can be time consuming at best. The ProVision Custom Graph Wizard lets…
Boomerang DNP3 Point Map 2.0
The Boomerang family of wireless voltage, current, and power monitors supports the DNP3 protocol for monitoring and control of a Boomerang when used as a DNP3 outstation. The original Boomerang…
SNTP Configuration for the Revolution
PMI's Revolution power quality recorders are available with Ethernet/networking capabilities which are easily configurable to allow quick connection and communication over a company's network. One of these network capabilities is…
Net Metering in ProVision
ProVision offers a wide variety of reports and graphs for displaying various types of power quality data. One of these is the power consumption report. Newly added to this report…
