MEASURED DATA
The range of measured data depends on connection for measurement and measurement
parameterization. Measured data are divided into data of continuous phenomena of vol-
tage quality, event data and recorder data.
Data of continuous phenomena of voltage quality (aggregation interval 10 min):
- Time of evaluation
- Voltage unbalance
- Frequency
- Voltage magnitude
- Voltage deviations U
over
, U
under
- Flicker P
st
and P
lt
- THD
U
- DC component, fundamental harmonic up to 125
th
harmonic of voltage
- Centered subgroups of interharmonic component of voltage up to the order of 125
- Level of voltage signals
- Flagged data
- Currents
- Basic to 125
th
harmonics of currents
- Centered subgroups of interharmonic I up to the order of 125
Data at events :
- Time of event
- Event duration
- Moments when the limits for interruption, dip and swell of voltage and current
are exceeded
- Residual and maximum values of voltage and current
- Curves of voltages U
RMS1/2
and currents I
RMS1/2
- Oscillogram of voltage and current curves during event
- Harmonic voltages and currents during event
