Power Quality
Interharmonics and RMS Variation
Interharmonics occur when a signal is present in a power system where the frequency is not an integer multiple of the 60 Hz line frequency. These can be generated from…
Line and Phase Voltage in PQ Canvass
PQ Canvass now supports viewing RMS Voltage in a virtual Delta hookup (Line-Line) when the device is hooked up to a Wye configuration (Line-Neutral) and initialized as such. This feature…
Voltage Imbalance and Its Impact on Waveform Distortion
Voltage imbalance, also referred to as voltage unbalance, is an important power quality issue that can lead to significant operational problems in customer equipment. It occurs when the magnitudes or…
PQ Canvass and Cybersecurity
PQ Canvass is PMI's next-generation web-enabled power monitoring and analysis platform. Deploying PQ Canvass as a web application provides a number of benefits: analyzing recordings while the recorder is still…
PMI View Feature Updates and Enhancements
Introduction PMI View for iOS continues to evolve with new features and improvements since our last white paper. This document highlights the significant additions that enhance your ability to perform…
Fourier Transform Intuition
Harmonic Analysis is a fundamental part of any power quality investigation. A good amount of information can be gained about a power signal by looking in the frequency domain at…
Auto-Correction of CT Hookup
Sometimes when hooking up CTs for a device, a user will inadvertently place the CTs in the wrong configuration. Maybe the channel 2 CT was placed on the third phase…
60Hz Phasors and Extended PQ Measurements
This white paper walks the reader through a method to take basic core PQ measurements and derive several other measurements (such as 60Hz power, Voltage and Current THD, distortion power…
Datacenter Power Consumption
The proliferation of digital technologies has driven rapid growth of data centers across the United States. These facilities, housing the servers that power the internet, cloud computing, and big data…
Symmetrical Components from Stripchart Data
Symmetrical components can be useful in a PQ investigation, especially in cases of voltage imbalance, where the customer's negative sequence current can help determine their contribution to the imbalance. Many…
Record, Diagnose and Troubleshoot 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…
