PrB | Page 62 of 148 Integration Time Under Steady Load: Reactive Energy As mentioned in the Active Energy Calculation section, the discrete time sample period (T) for the accumulation register is 1.22 μs (5/MCLK). With full-scale sinusoidal signals on the analog inputs and the VARGAIN and VARDIV registers set to 0x000, the integration time before the reactive energy register overflows is calculated in Equation 24. Time = min 82 . 6 sec 6 . 409 s 22 . 1 0xCCCCD FFFF FFFF, 0xFFFF, = = μ × (24) When VARDIV is set to a value different from 0, the integration time varies, as shown in Equation 25. VARDIV Time Time WDIV × = =0 (25) Reactive Energy Accumulation Modes VAR Signed Accumulation Mode The ADE5569/ADE5169 reactive energy default accumulation mode is a signed accumulation based on the reactive power information. VAR Antitamper Accumulation Mode The ADE5569/ADE5169 are placed in VAR antitamper accumula- tion mode by setting the SAVARM bit in the ACCMODE register (0x0F). In this mode, the reactive power is accumulated depending on the sign of the active power. When active power is positive, the reactive power is added as it is to the reactive energy register. When active power is negative, the reactive power is subtracted from the reactive energy accumulator (see Figure 51). The CF pulse also reflects this accumulation method when in this mode. The default setting for this mode is off. Transitions in the direction of power flow and no load threshold are active in this mode.
