Possible states for the +/-P indicators are:
Both off
No Active Energy is being consumed.
+P ‘on’ –P ‘off’
All energy being consumed is in a positive
direction.
-P ‘on’ +P ‘off’
All energy being consumed is in a negative
direction.
+P ‘on’ –P flashing
Majority of the energy is Positive with some
negative (
only
in three-phase four-wire circuit;
only
with magnitude summation).
-P ‘on’ +P flashing
Majority of the energy is Negative with some
positive (
only
in three-phase four-wire circuit;
only
with magnitude summation).
Example C below is the reciprocal of the previous. Active energy is now
zero (circle symbol and no direction indicators (anti-creep mode), but
Reactive energy is now being recorded. Again the arrow and +Q
symbols are flashing.
Also notice that the displayed register is now a positive total kVArh
register.
Example C (OBIS code 3.8.1)
Possible states for the +/-Q indicators are:
Both off
No Reactive Energy is being consumed.
+Q ‘on’ –Q ‘off’
All energy being consumed is in a positive
direction.
-Q ‘on’ +Q ‘off’
All energy being consumed is in a negative
direction.
+Q ‘on’ –Q flashing
Majority of the energy is Positive with some
negative (
only
in three-phase four-wire circuit;
only
with magnitude summation).
-Q ‘on’ +Q flashing
Majority of the energy is Negative with some
positive (
only
in three-phase four-wire circuit;
only
with magnitude summation).
The Energy Direction Indicators (or anti creep indicators) will always be
displayed. These indicators, along with the phase powered indicators
(L1, L2, L3), battery monitor and rate indicators (see below) provide the
user with a quick overall status of the meter.
