    problem in ade7758 voltage filter network

    Hi, I am Amna .i am working on ade7758 evaluation board which is an energy meter. in voltage filter network neutral is shot to agndi.e. agnd should appear at tp13 but its not happening. If I measure tp17 wrt tp13 i.e. vap wrt vn I get varying readings but if I measure vap wrt agnd that reading...

    can a parallel array of 28 resistors act as BURDEN RERSISTOR

    I WANT TO INTERFACE A 200:5 CURRENT TRANSFORMER WITH A LOW POWER CIRCUITRY SUCH AS ADE7758 WHICH REQUIRES .5 V PEAK MAX AS AN INPUT OF ITS ADC.I CALCULATED THE BURDEN RESISTOR TO BE 36 mOHM WHICH IS NOT AVAILABLE SO I THOUGHT OF PLACING AN ARRAY OF 28 PARALLEL RESISTORS OF 1 OHM SO THAT THEIR...
