If current falls below the low limit for the current measurement, the following measured
values and derived variables of the affected phase are reset.
● Effective current value
● Neutral current
● Active power
● Reactive power
● Apparent power
● Phase angle
● Power factor
A moving mean value is formed from the power values and they only become "0" after a
corresponding time. The energy meters for active, reactive and apparent energy as well as
the operating hours counters do not count any longer.
Further information can be found under Low limit for measuring current undershot
(Page 125).
Enable operating hours counter
Enable the operating hours counter. The counting starts from the configurable low limit of the
current measurement. The counter can be reset or pre-assigned using data record or output
bit.
Enable gate of operating hours counter
Enable the gate for the operating hours counter. When the gate is activated, the operating
hours counter only counts when the corresponding output data bit (DQ bit) is set to "1".
Current transformer primary current
Enter the nominal value for the primary current of the current transformer used. The
transformer ratio is calculated from the primary and secondary current.
Current transformer secondary current
Enter the nominal value for the secondary current (1 A or 5 A) of the current transformer
used. The transformer ratio is calculated from the primary and secondary current.
Reverse current direction
Setting to determine whether or not to reverse the direction of current.
In the event of inadvertent incorrect connection, this parameter can be used to correct the
measured values, thus saving the hassle of rewiring. The direction of the current is only
evident from the power measurement values. The current measurement value is an rms
value.
