Understanding Vector Diagrams
This whitepaper will discuss what vector diagrams are, what they display, and how PMI's power quality recorders and ProVision can provide the user with this information.
Using 3D Graphs in ProVision
Power quality data in ProVision is presented in two distinct formats: as either a text-based report, or as a graphical image. The latter category, referred to in ProVision as graphs,…
Understanding Recording Modes
Recorders connected in ProVision have two primary modes: Standby mode and Ready mode. Each of these modes has a distinct purpose, and some recorder operations in ProVision require the recorder…
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…
Measuring Abnormal Voltage
The Abnormal Voltage Report is one of the "Triggered Event" reports in ProVision and it is used to determine whether voltage drifted outside the thresholds during the recording session. Usually…
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.…
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…
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.…
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…
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…
