Measuring PLC AMR Signals with the Revolution
Many AMR (automatic meter reading) systems rely on PLC (power line communication) signals for data transfer. These signals travel on the 60Hz distribution network and can be affected by power…
Revolution Access via the Canvass Web Interface
PMI is excited to announce support for Revolution analyzers in Canvass, our cloud-based data analysis software. Utilizing Revolutions with Canvass makes it possible to view graph types that are not…
ProVision Recording Inspector
The Recording Inspector is a new ProVision feature for finding lost files, classifying files by category or recorded data, and combing through large file sets for a certain data type.…
Three-Phase Motor Start Causes Voltage Dips
In many cases when a local utility customer complains of voltage problems, it can often be traced back to a neighboring electrical load change that has caused voltage dips on…
Using the CBEMA Curve in ProVision
The ability to record CBEMA data points is a feature that is new in PMI Revolution recorders with firmware 5.66 or later. It is also available as part of a…
Boomerang Networking Options for SCADA and Canvass
PMI's Boomerang monitor is a versatile product, with configurations capable of sampling voltage, current and power. These analyzers are accompanied by powerful analysis software through PMI's Canvass web application or…
Interharmonics in ProVision
Recording interharmonic data is a new feature available in certain PMI recorders. Recording of interharmonics is a new feature in the Revolution, and requires at least the firmware version 5.66…
Understanding Telephone Interference Factor
Harmonic distortion that is produced from power conversion systems can cause interference on analog telephone lines. The degree of telephone interference can be expressed in terms of the Telephone Interference…
Measuring Neutral Voltage Drop with the Eagle 120
This paper shows why the Eagle 120 measures a different voltage potential between the neutral and ground and why the neutral's voltage is elevated above ground under a load condition.…
CBEMA and ITIC Curves
The CBEMA and ITIC curves are both used to visibly represent voltage events. The terms and associated curves are used somewhat interchangeably even though there are subtle differences between the…
Voltage and Current Out of Limits Reports
This white paper covers Out of Limits Reports, their main benefits, and how and when to use them. Out of Limits Reports offer a quick way to gauge power quality…
