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…
Upgrading ProVision
ProVision, the power quality diagnostic software provided by Power Monitors, is consistently maintained and updated as new features are added and existing ones are updated. Some of these are minor,…
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…
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…
Four-Wire Delta Voltage Unbalance
Voltage unbalance in a four-wire or "high leg" delta can be tricky to measure. A 4-wire delta often involves unbalanced impedances, and phase shifts in the hot leg are common.…
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…
Steady State vs. Transient Harmonics
A harmonic analysis is a powerful method for analyzing waveform distortion, given the periodic nature of most nonlinear loads. Steady-state harmonic tools are sometimes extended for use with waveform events…
Capturing Oscillatory Transients
Oscillatory transients are caused by switching operations, nearby lightning strikes, or other impulsive noise exciting electrical resonances present on the network. The most common in the distribution system is defined…
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…
