10 / 10 page REV. PrB 08/01 PRELIMINARY TECHNICAL DATA ADE7752 –10– NO LOAD THRESHOLD The ADE7752 also includes a “no load threshold” and “start-up current” feature that will eliminate any creep effects in the meter. The ADE7752 is designed to issue a minimum output frequency. Any load generating a frequency lower than this minimum frequency will not cause a pulse to be issued on F1, F2 or CF. The minimum output frequency is given as 0.0007% of the full-scale output frequency for each of the F1–5 frequency selections—see Table II. For example, an energy meter with a meter constant of 100 imp/ kWhr on F1, F2 using F2 (4.77 Hz), the minimum output frequency at F1 or F2 would be 0.0007% of 4.77 Hz or 33.3 x 10 –6 Hz. This would be 533 x 10–6 Hz at CF (16 x F1 Hz). In this example the no load threshold would be equivalent to 1.2 W of load or a start-up current of 5.5 mA at 220 V. REVERSE 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° i.e. ΦA or ΦB or ΦC > 90°. This mechanism can detect wrong connection of the meter or generation of Active Energy. The REVP pin output will go 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 as a pulse is issued on CF. If several phases measure negative power, the REVP pin output will stay low until all the phases measure positive power.
