NEGATIVE POWER INFORMATION
The ADE7752 detects when the current and voltage channels of
any of the three phase inputs have a phase difference greater
than 90°: ϕA or ϕBB or ϕC > 90°. This mechanism can detect
wrong connection of the meter or generation of active energy.
The REVP pin output goes active high when negative power is
detected on any of the three phase inputs. If positive active
energy is detected on all the three phases, REVP pin output is low.
ADE7752/ADE7752A
The REVP pin output changes state at the same time a pulse is
issued on CF. If several phases measure negative power, the
REVP pin output stays high until all the phases measure
positive power. If a phase has gone below the no load threshold,
REVP detection on this phase is disabled. REVP detection on
this phase resumes when the power returns out of no load
condition. See the No Load Threshold section.
