Historic data logs
Three historic data logs are used to record standard power system quantities, such as
phase current, phase voltage and power factor. These logs are labeled Hist Mean Log,
Hist High Log, and Hist Low Log. By default, they log the following values:
Hist Mean Log Hist High Log Hist Low Log
Vll ab mean I avg mean Vll ab high I avg high Vll ab low I avg low
Vll bc mean I 4 mean Vll bc high I 4 high Vll bc low I 4 low
Vll ca mean kW tot mean Vll ca high kW tot high Vll ca low kW tot low
Vll avg mean kVAR tot
mean Vll avg high kVAR tot high Vll avg low kVAR tot low
V unbal mean kVA tot mean V unbal high kVA tot high V unbal low kVA tot low
Ia mean PF lag mean Ia high PF lag high Ia low PF lag low
Ib mean PF lead mean Ib high PF lead high Ib low PF lead low
Ic mean Freq mean Ic high Freq high Ic low Freq low
Loss log
The Loss Log is configured to record loss values. 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. By default, they log the following values:
