Logging

Loss log

The Loss Log (Data Rec 9) is configured to record loss values. Factory settings for this data
recorder:
• Log depth = 3360 records (35 days)
• Interval = 900 seconds (15 minutes)
By default, it logs the following values:
Parameter
MU Ia^2h int
MU Ib^2h int
MU Ic^2h int
MU Vllab^2h int
MU Vllbc^2h int
MU Vllca^2h int
MU Vln a^2h int
MU Vln b^2h int
MU Vln c^2h int

Harmonics logs

Two harmonics logs record various harmonics data, including K-factor and Total Harmonic
Distortion (THD). These recorders are labeled Harm Mean Log and Harm High Log. Factory
settings for these data recorders:
• Log depth = 840 records (35 days)
• Interval = 3600 seconds (1 hour)
By default, they log the following values:
V1 THD mean
V2 THD mean
V3 THD mean
V1 THD high
V2 THD high
V3 THD high
