PQ Configuration
Page 48 from 69
Limits and parameters for the evaluation of the power quality (PQ) are configured here according to individual criteria.
The PQ configuration is done either via Modbus or via the cloud (= default setting).
The path can be changed in the device settings under general at "Path for PQ configuration".
11.1 General
Observation period
The status of the power quality is evaluated over this period. One day or one week can be set.
Observation start
Can be set to "Fix" (manually adjustable start time) or to "Auto" (next possible start time).
Consider flagged PQ intervals for event counter
Measuring intervals can be marked according to the flagging concept described in EN 61000-4-30.
Flagged data indicate that they may be unreliable. The user is free to take them into account or not.
Periods
For various power quality characteristics, time periods can be defined within an observation period in which the limits must be observed.
This period is specified in % of the selected observation period and indirectly defines the permissible number of events within an
observation period.
11.2 Voltage magnitude
The measured voltage magnitude is defined by the rms value of the voltage between the outer and neutral conductor (or outer and PEN
conductor). It is averaged over a time window of 10 minutes.
Limits
Two sets of limit values are available. For everyone there is a minimum and a maximum as well as a period in which the limits must be
adhered to before the violation occurs. The period is given in % of the selected observation period.
