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 F
1–5
frequency selections—see Table II. For
example, an energy meter with a meter constant of 100 imp/
kWhr on F1, F2 using F
2
(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.
Φ
A
or
Φ
B
or
Φ
C
> 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.
