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…
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…
