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 Description
MU Ia^2h int Phase A interval current squared hours
MU Ib^2h int Phase B interval current squared hours
MU Ic^2h int Phase C interval current squared hours
MU Vllab^2h int Phase A interval voltage Line-to-Line squared hours
MU Vllbc^2h int Phase B interval voltage Line-to-Line squared hours
MU Vllca^2h int Phase C interval voltage Line-to-Line squared hours
MU Vln a^2h int Phase A interval voltage Line-to-Neutral squared hours
MU Vln b^2h int Phase B interval voltage Line-to-Neutral squared hours
MU Vln c^2h int Phase C interval voltage Line-to-Neutral squared hours
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:
Harm Mean Log (Data Rec 7)
V1 THD mean I1 THD mean I1 K Fac mean
V2 THD mean I2 THD mean I2 K Fac mean
V3 THD mean I3 THD mean I3 K Fac mean
