Historic Data Logging
Three data recorders are used to record “standard” power system quantities, such
as phase current, phase voltage and power factor. These recorders are labeled Hist
Mean Log, Hist High Log, and Hist Low Log. By default, they log the following ION
output register values:
as phase current, phase voltage and power factor. These recorders are labeled Hist
Mean Log, Hist High Log, and Hist Low Log. By default, they log the following ION
output register values:
Loss Log
The Loss Log recorder is configured to record loss values. By default, it logs the
following ION parameters:
following ION parameters:
Harmonics Logging
Two recorders provide various harmonics logs, including K-factor and Total
Harmonics Distortion (THD). These recorders are labeled Harm Mean Log and
Harm High Log. By default, they log the following ION output register values:
