ADE7758 APCF pulses in pure reactive points

Question asked by kbj on Jul 16, 2012

I am developing an indirect CT operated 5A(6A) IEC energy meter using ADE7758.

It is working properly except  in one point which it works a little weird.

While testing pure reactive points for currents above 1A the active output pulse( APCF ) starts blinking; the worst thing is that the active energy registers inside the chip and the APCF pulses are not equal.

Could any one help me about it?
