Impact Loading – PQ Canvass
Impact loading occurs from the inrush current of large motors, welding apparatus, electric arc furnaces, or similar loads. The current pulses are less than short circuit values but may be…
IEEE 1250 Overview: An Introduction to Power Quality
Whether you are new to the study of power quality, or an experienced PQ pro looking for a quick reference, IEEE Standard 1250 is the place to start. IEEE 1250…
Viewing Power Consumption in the Cloud
Energy usage metering (in kWh) is now available at-a-glance from the PMI Canvass web application. This new feature will save you time while you diagnose internal and customer-facing issues by…
Wireless Power Quality
The time and cost of deploying PQ instrumentation only to return later in order to retrieve it (without the guarantee that the PQ anomaly has occurred) is often times exorbitant.…
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…
Understanding PMI Data Record Types – Part 1
The job of any power monitor is to record all interesting data and leave unrecorded the vast majority of boring, unremarkable data. The tricky part for a monitor is deciding…
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…
