Introduction to Residential Photovoltaic Systems
This white paper explains the basic elements that make up a PV system– including the different types, how they work, and what impact they have on both the grid and…
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…
Understanding Triplen Harmonics
With the push for energy efficiency comes the proliferation of non-linear loads whose overall effect on the power transmission system may not always be as beneficial as originally intended. The…
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…
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…
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…
Ring Frequency, PF and CF from Waveform Capture
With the Point Table in the Waveform Capture function of ProVision, it is possible to estimate the ring frequency, phase shift, power factor, and crest factor of a waveform.
Analyzing Motor Startups with Event Capture
This paper describes how Event Capture can be used to analyze motor startups and covers the typical initial settings for capturing and analyzing a motor startup. All PMI recorders, old…
Techniques for Analyzing Motor Startups
This paper covers the setup fundamentals and techniques required to obtain the high-quality waveform capture needed to analyze a motor startup. It also reviews the basic electrical characteristics of a…
Measuring Neutral Voltage Drop with the Eagle 120
This paper shows why the Eagle 120 measures a different voltage potential between the neutral and ground and why the neutral's voltage is elevated above ground under a load condition.…
Understanding IEEE Flicker, IFL, Pst, Plt
This white paper covers and explains three of IEEE's most common Flicker definitions: IFL, Pst and Plt. The GE Flicker Curve and how other measurements standards compare to the GE…
