In a normal distribution network, the fundamental frequency is that of the voltage driving source, nominally 60Hz. Steady state deviations from the ideal 60 Hz sine wave shape are “periodic,”…

PQ Canvass — Getting Started
Power Monitors’ PQ Canvass is the premiere way to view and analyze power quality data. Born from Canvass, our first generation cloud-based system, PQ Canvass is a power platform to…
Voltage Regulation Analysis With Daily Profiles
If there were no variations in distribution load, system voltage regulation would be a simple task. But Ohm’s law dictates that a change in load produces a change in delivered…
Defining Interharmonics
Interharmonics are frequency components at non-integer harmonics of the line frequency. The proliferation of large DC-converter variable speed drives and wind/solar inverter generation has led to an increase in interharmonic…
