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
Harm High Log (Data Rec 8)
V1 THD high I1 THD high I1 K Fac high
V2 THD high I2 THD high I2 K Fac high
V3 THD high I3 THD high I3 K Fac high
Energy and demand log
The EgyDmd Log (Data Rec 10) records energy and demand data used by energy
management software to generate reports. 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
kWh del Active energy delivered
kWh rec Active energy received
kWh del-rec Active energy delivered minus received
kVARh del Reactive energy delivered
kVARh rec Reactive energyreceived
kVARh del-rec Reactive energy delivered minus received
kVAh del+rec Apparent energy delivered plus received
kW sd del-rec Active power demand delivered minus received
kVAR sd del-rec Reactive power demand delivered minus received
kVA sd del+rec Apparent power demand delivered plus received
Daily nominal log
The DailyNom Log (Data Rec 39) provides information about the meter’s nominal
settings. Factory settings for this data recorder:
• Log depth = 450 records
