Reactive Energy
Reactive energy is only available in line accumulation mode in
the ADE7753. The accumulated reactive energy over LINECYC
number of half line cycles is stored in the LVARENERGY register.
by comparing the nominal reactive energy accumulation rate to
the expected value. The attenuation correction factor is multi-
plied by the contents of the LVARENERGY register, with the
ADE7753 in line accumulation mode.
In the ADE7753, a low-pass filter at 2 Hz on the current
channel is implemented for the reactive power calculation. This
provides the 90 degree phase shift needed to calculate the reactive
power. This filter introduces 1/f attenuation in the reactive
energy accumulated. Compensation for this attenuation can be
done externally in a microcontroller. The microcontroller can
use the LVARENERGY register in order to produce a pulse
output similar to the CF pulse for reactive energy.
To create a VAR pulse, an impulse/VARh constant must be
determined. The 1/f attenuation correction factor is determined
