Harmon.vdf Template
This template contains the limit values according to EN 50160. A recording is started, if a
limit value for voltage is exceeded. The system thereby monitors the 25 harmonics of the
voltage and records 3-sec values. These trigger settings thus register any exceeding of the
limit values of the voltage harmonics.
PC.vdf Template
This template has been devised for the detection of problems with the PC, voltage dips,
and/or current fluctuations. It responds to under-voltages in the phases, voltage
fluctuations in the neutral conductor, and wave shape faults in the phase voltages and at
the neutral conductor as well as voltage transients.
Rundst.vdf Template
This template shows sample settings for a ripple control system. The ripple control signal
frequency (center frequency) and the trigger level must be adjusted to the actual
requirements.
Trans.vdf Template
Transients over 50 V trigger the recording of rapid sample values, oscilloscope and rms
values.
These settings provide the recording of non-repeated, rapid events in the network, and is
triggered by rapid voltage changes (over voltage and under voltage). The transient and
rms data are recorded. The system detects any switching events. Peaks over 358 V trigger
the recording of oscilloscope and rms values.
Overview.vdf Template
RMS values over 253 V, sample values over 358 V, or transients over 50 V trigger the
recording of oscilloscope and rms values.
These settings provide the recording of non-repeated, rapid events in the network, and is
triggered by rapid voltage changes (over voltage). The transient and rms values are
recorded. The system detects any switching events. Peaks over 358 V trigger the
recording of oscilloscope and rms values.
