Item Description
Demand Interval The Demand Interval applies to the Demand Present
Primary Current (Amps) parameter and the Demand
History parameters. The Demand Interval can be set
to 5, 10, 15, 30, and 60 minutes.
Demand Present Primary Current The Demand Present Primary Current parameter
value follows the concept of a lagged demand meter.
The demand time interval is selected by the user as
5, 10, 15, 30 or 60 minutes. This is the time it takes for
a thermal meter to indicate 90% of a change in load.
Load Voltage Displays the real-time measured value of voltage at
the Tapchanger or transformer and includes any
corrections made using the user selected VT
Correction Voltage.
Primary Current Displays the calculated primary demand current
based on the user-selected current multiplier and
measured secondary current.
Primary Watts Displays the real time demand value base on the
user-selected voltage and current multipliers; VT
configuration (line-to-ground or lineto- line), single-
phase or three-phase, and measured secondary
voltage and current.
Primary VAr Displays the real time demand value based on the
user-selected voltage and current multipliers, VT
configuration (line-to-ground or line-to-line), single-
phase or three-phase, and measured secondary
voltage and current.
Primary VA Displays the real time demand value based on the
user-selected voltage and current multipliers, VT
configuration (line-to-ground or lineto- line), single-
phase or three-phase, and measured secondary
voltage and current.
3.8.5 Demand history/energy metering
All demand history (single phase) and Energy Metering Values include the date and time
at which each occurred. A drag hand value is the maximum or minimum value of a
measured quantity recorded since the last reset.
