NEGATIVE POWER INFORMATION

The ADE7752 detects when the current and voltage channels of

any of the three phase inputs have a phase difference greater

B

C

> 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.

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.
