Hello,

 

Most of the AD metering IC has 'Positive only accumulation mode' for measuring active power & REVP pin to indicate negative power. What is the diff in having and not having positive only accumulation mode.?? For instance ADE7953 has active low REPV pin. If I want to measure negative power, does such IC provide this function?? Means consider ADE79xx front end doesnot have positive only accu. mode but has pin to indicate reverse power. So in this case, if input power is negative, will there be pulses(to measure power from CF1 pin) or only REVP pin will change the state and there will be no output pulses on CF1/CF2??
