Understanding Total Harmonic Distortion
This paper discusses the causes of Total Harmonic Distortion, how it is calculated, measured, and how it can impact a power distribution system.
Municipal Golf Course Suffers Catastrophic Damage From Overheated Neutral
In this modern world of power we see more and more desire to improve efficiency and reduce costs, which leads to decisions on what equipment to choose to meet these…
Adjusting Waveform Capture Sampling Rates
Waveform capture is one of the most important data types available for PQ analysis. The sample-level data provides detailed information for voltage disturbances such as oscillatory transients, notches, sub-cycle overvoltages…
Voltage Notching Effects on Harmonic Distortion
Notching is a voltage waveform distortion resulting from short-duration high current pulses. These distortions typically present themselves graphically as a “notch” in the time domain representation of the waveform. The…
Seven Common Utility Distribution Challenges: How the Boomerang and Canvass Can Help
Here's our quick list of 7 common utility distribution challenges. These shouldn't come as a surprise to anyone in the industry as utility companies are experiencing more challenges than ever.…
Sampling Rate in PQ Recorders
A common specification in power quality recorders such as PMI's Revolution, Guardian, or Eagle products is the sampling rate of the device. Users know this is an important number and…
Advanced Daily Profile Analysis with Canvass
The Daily Profiles graph is likely one of the most underutilized Canvass graphing features. This particular graph is great for identifying long term (and even short term) trends, many of…
Flicker Investigation Strategy
Flicker is defined as fluctuation or wavering in visible light intensity due to voltage variations. These variations in voltage are caused by fluctuations in the load through the system source…
