A 3-phase voltage system (L1, L2, L3) can be measured with the help of the Siemens Sentron PAC3200. The
following electrical quantities can be read from the measuring instrument's multi-line display: voltage,
current, apparent, active and reactive power, power factor, frequency, voltage/current distortion factor and
asymmetrical voltage/current logging, and the following additional functions are also available: minimum-
maximum values, active and reactive energy, dual tariff recording, average power demand MIN/MAX,
operating hours meter, energy meter and limit value monitoring.
Contactless current measurement is implemented with the help of current transformers.
The transformation ratio is 35:1.
The protective conductor must be plugged in first. Continuity to the protective
conductor of the electrical installation must be assured.
