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.…
Cell, WiFi, and More with the New Cell Guardian Meter Socket Recorder
PMI has just introduced a major redesign of the Guardian meter socket power quality analyzer. This white paper will focus specifically on the new Cell Guardian recorder and cover the…
Electrical Undervoltage and Power Quality
In this whitepaper, the term undervoltage is explained, some typical causes of undervoltages are given, and the effects of undervoltage on customer loads is described. IEEE 1159-2009, IEEE Recommended Practice…
Hardware for Power Quality and Distribution Monitoring
PMI offers an array of monitoring devices for just about any utility distribution monitoring need. Data needs, location, and communications requirements are all factors involved in selecting the right monitor…
Software to Diagnose Power Quality Issues
Data analysis is the key to understanding and solving engineering problems on the distribution system. PMI offers three types of software tools to speed the analysis process, and help manage…
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…
Canvass and Cybersecurity

Hidden Delta Voltage Unbalance
Voltage unbalance can cause severe heating in motors and large DC power converters. Although most voltage unbalance is caused by unequal loading among phases, shifts in voltage phase angle can…
Voltage and Current Scaling in Canvass
The ability to store and apply multiplicative scaling factors to voltage, current, and power data is a new feature recently added to the cloud-based Canvass system. Scale factors have a…
Using TLAR CTs
TLARs are PMI's iron core CT (Current Transformer) clamps, available in various probe and channel configurations. These clamps are used for lower range current measurements, with ranges of 20A or…
Photovoltaic Monitoring with Canvass
