ADE7752/ADE7752A
MODE SELECTION OF THE SUM OF THE THREE
ACTIVE ENERGIES
The ADE7752 can be configured to execute the arithmetic sum
of the three active energies, Wh = Wh ?A + Wh ?B + Wh ?C , or the
sum of the absolute value of these energies, Wh = | Wh ?A | +
| Wh ?B | + | Wh ?C |. The selection between the two modes can be
made by setting the ABS pin. Logic high and logic low applied
on the ABS pin correspond to the arithmetic sum and the sum
of absolute values, respectively.
When the sum of the absolute values is selected, the active
energy from each phase is always counted positive in the total
active energy. It is particularly useful in 3-phase 4-wire installa-
tion where the sign of the active power should always be the
same. If the meter is misconnected to the power lines, (for
The sum of the absolute values assures that the active energy
recorded represents the actual active energy delivered. In this
mode, the reverse power pin still detects when negative power is
present on any of the three phase inputs.
POWER MEASUREMENT CONSIDERATIONS
Calculating and displaying power information always has some
associated ripple that depends on the integration period used in
the MCU to determine average power as well as the load. For
example, at light loads, the output frequency may be 10 Hz.
With an integration period of 2 seconds, only about 20 pulses
are counted. The possibility of missing one pulse always exists
since the ADE7752 output frequency is running asynchro-
nously to the MCU timer. This would result in a 1-in-20 or
5% error in the power measurement.
instance, if CT is connected in the wrong direction), the total
active energy recorded without this solution can be reduced by
two-thirds.
