Since the sinusoidal component is integrated over an integer

Figure 44. Line Cycle Active Energy Accumulation
Note that in this mode, the 16-bit LINCYC register can hold a
maximum value of 65,535. In other words, the line energy
accumulation mode can be used to accumulate active energy for
a maximum duration over 65,535 half line cycles. At 60 Hz line
frequency, it translates to a total duration of 65,535/120 Hz =
546 seconds.
REACTIVE POWER CALCULATION
Reactive power is defined as the product of the voltage and
current waveforms when one of these signals is phase-shifted by
90°. The resulting waveform is called the instantaneous reactive
power signal. Equation 25 gives an expression for the instanta-
neous reactive power signal in an ac system when the phase of
the current channel is shifted by +90°.
