Monitoring and metering
The sequence of events logging and the recording of the
waveform capture (24 samples/power cycle), provide the user
with all of the useful information on the electrical network
status. This features allow continual and full monitoring in
normal operation as well as in the event of a system fault.
High accuracy measurements may replace measuring instruments
and transducers.
Direct measurements
For every input channel, the amplitude (RMS), phase and period
for the fundamental and harmonic components are provided.
- Frequency,
- Phase & residual currents and voltages,
- Harmonic components,
- Directional currents, etc.
Computed measurements
On the basis of the direct measurements, the following are
processed: phase-to-phase voltages, residual voltage and
current, sequence components, powers, impedances, energy,
demand values (equivalent thermal current, fixed, rolling,
peak and minimum demand of phase currents, powers, etc...).
Besides the input values, a lot of relevant information are
available; i.e: tripping counters, number of CB close
commands, duration of the CB open and close operations, number
of automatic reclosing commands, date and time, relay ID data,
identification code, serial number, firmware version, rated
parameters, etc.
