4. Service description
4.1 Measuring the power quality according to EN 61000-4-30, class A
Monitored are: Voltage magnitude, frequency, flicker, voltage dips, voltage swells, interruption, unbalance, harmonics, interharmonics,
mains signalling voltages, rapid voltage changes.
Measurement/recording Analysis and evaluation
Power quality according to EN 61000-4-30:2015, class A
According to standard EN 50160 and
at the same time according to individual specifications
4.2 Additional measurement capabilities
Measurement/recording Analysis and evaluation
Impulse current 8/20 µs and 10/350 µs to 100 kA * By maximum, duration, rise time, and single/sum charge.
Current, power, energy via up to 4 current sensors
(Rogowski coils or split core current transformers)
Limit values for current, power (P, Q, S), current direction, zero current
and energy (global) can be parameterized separately for each phase or
the neutral conductor
Power frequency overvoltages (POP)
According to standard EN 50550 and also individually with differentia-
tion exceedance/undershot
Digital states at 3 inputs
According to state/change with counter function.
After status / change with counter function. The inputs can be logically
linked to one another and to other device functions.
* Variant with impulse current measurement expected to be available from Q4 - 2021
