Strategies for Investigating Flicker
Investigating flicker issues with PMI recorders can be straightforward if the right data is collected, and analyzed with ProVision. By enabling and examining Pst and IFL flicker data, in addition…
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…
Understanding Real, Reactive, and Apparent Power
This white paper defines the differences between Real Power, Reactive Power, and Apparent Power in terms used by the power distribution industry. Here the relationships between these different types of…
Understanding Harmonics
With the increase in nonlinear loads (VFDs, high efficiency heat pumps, electronic power supplies, etc.) and the reduction in excess distribution capacity, harmonic distortion is an increasingly common power quality…
Introduction to Electric Vehicle Systems
This paper, the first of a multi-part series, covers the fundamentals of electric vehicle charging stations, charge modes, plug configurations, levels, and basic operation. Electric vehicles, although very efficient, are…
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…
In Place Updating with ProVision
ProVision, the power quality data analysis software provided by PMI, is constantly modified to meet the changing needs of engineers and technicians, and to ensure compatibility with other hardware and…
Using Loss of Periodic Load to Trigger Email Alerts
Boomerang triggering mechanisms are most often used for voltage monitoring, detecting overcurrent/high load conditions, or complete loss of load. However, the advanced triggering features in the Boomerang allow for more…
Upgrading from WinScan to ProVision
As hardware improvements are made over time, the software that communicates with and controls that hardware must also evolve. Improvements in hardware, operating systems and most importantly, user feedback all…
