Using PMI Recorders
Overcurrent Protection with Fused Leads
PMI offers a fused voltage lead kit for increased safety with the Revolution and Eagle power recorders. Although not required to meet UL safety standards with these recorders, the fused…
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…
Approaching Power Quality Monitoring Site-Work
Power quality (PQ) monitoring provides insightful information that can be used to detect industrial and residential power disturbances, and provide clues for mitigation and problem resolution. Having the proper power…
Evolution of Power Quality Recording
Power quality analysis is a rapidly changing field, and is intrinsically linked to advances in digital technology. From its humble beginnings as analogue recorders that wrote a single voltage directly…
Predictive Power Monitoring
Power Quality Monitoring data can be used to detect and identify potential problems either before equipment begins to fail or before it fails completely. Symptoms recorded by PQ monitors can…
Minimizing Data Usage with DNP3
The DNP3 protocol was originally developed back in the day when a wired connection to devices was the norm. The protocol was designed to be robust and very reliable but…
The Basics of Power Quality Monitoring
PMI's line of power quality (PQ) monitoring tools can provide insightful information that can be used to detect industrial and residential power disturbances such as sags, swells, transients, waveform distortions,…
Vector Diagrams for Commonly Used Power Circuits
This white paper describes vectors and vector diagrams. It provides the vector diagrams and sketches of the connections required for correctly installing a power monitor on commonly used power circuit…
Two Minute Countdown
Prior to recording, PMI recorders have a countdown interval of time used for initialization called the "Two Minute Countdown". This period of time is used to verify proper hookup, change…
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 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.…
