Demand:
This meter consists of several types of demand calculation: total active power
demand, total reactive power demand, total apparent power demand, phase A
current demand, phase B current demand, and phase C current demand. When
demand is reset, demand memory registers are set as 0.
Demand calculating mode can be set as sliding window and thermal according
to user. The figure 4-7 shows how it works.
When using the sliding window interval method, user selects an interval from
1 to 30 minutes, which is the period of the calculation. The demand updates
every 1 minute as the window slides once.
Thermal demand method calculates the demand based on a thermal response
which mimics a thermal demand meter. User selects the period for the
calculation and the demand updates at the end of each period.
Energy:
This meter measures and accumulates energy in different directions (import and
export). For real-time energy monitoring, it accumulates energy for kWh, kvarh
and kVAh continuous (since its last reset).
Calculating mode
1. User can select different energy calculating modes, fundamental based(not
applicable to
Acuvim IIR/IIE/IIW
) or full-wave based either from the meter front
or via communication. Fundamental based calculating is used to accumulate
energy without taking harmonics into consideration while full-wave based
calculating is used to accumulate energy including fundamental and harmonics.
Note: When fundamental based calculating mode is selected, PF calculation will
be based on the fundamental wave.
