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…
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…
Using Current Clamps
Measuring the current of residential, commercial or industrial applications is vital to get a complete power quality picture. This white paper covers various topics to effectively utilize the different types…
End-to-End Boomerang Cybersecurity
Power Monitors Inc.'s Boomerang voltage/current/power sensor, and Canvass, the web-based power quality analysis application is a system for gathering and analyzing data, especially over long periods of time. This long-term…
Power Quality Recorder Setup Basics
PMI recorders are capable of storing a large amount of data. The recording setup stored in the device determines the data that will be captured during a recording session as…
Power Transformer K-Factor
In this white paper I review K-factor in regards to power transformers, how K-factor is defined and calculated and how K-factor is used. K-factor is a way of rating or…
Disconnecting a Power Quality Recorder
This whitepaper covers the proper method used to disconnect power quality recorders and remove them safely from their location. Following the proper disconnection sequence eliminates or minimizes generating and recording…
Stripchart Graphing in Canvass
The Boomerang is a device developed by Power Monitors for the purpose of allowing continuous monitoring of voltage, current, and power data. The Canvass web application and data storage service…
Estimating THD with Power Factor Histograms
In the previous whitepaper Estimating THD with PF and DPF, a technique for estimating THD was shown given power factor and displacement power factor stripchart data. In many case, there's…
Per-Unit Analysis with ProVision
A per-unit scaling system simplifies many AC power analysis tasks. Eliminating transformer ratios, normalizing power values to equipment ratings, and allowing for like-to-like comparisons of differing nominals are just three…
Provisioning Boomerangs with a cellular data plan for Canvass and/or SCADA Systems
The Boomerang is one of the newest power quality measurement offerings by PMI. Capable of measuring voltage, current and real power, the Boomerang comes in multiple different measurement configurations and…
