1.3 ISTAT i4Mx Family
The i4Mx fa
mily consists of 3-phase and single phase transducers all of which are 0.5%
multifunction instruments. This manual details the single phase transducer models i4MC
and i4MV
1.3.1 i4MV class 0.5 Voltage Transducer.
i4MV is intended for measuring and monitoring single-phase voltages, both phase-neutral
and phase-phase. The voltage input is electrically insulated from the system by means of a
voltage transformer. It measures true RMS voltage values by means of fast sampling of the
input voltage signals, which makes it suitable for acquisition of transient events. A built-in
microcontroller calculates the measurands (voltage, frequency) from the measured signals.
The measurands can then be converted into load independent DC current or voltage which
is proportional to the true RMS measured value.
1.3.2 i4MC class 0.5 Current transducer
i4MC is intended for measuring and monitoring single-phase electrical power networks. The
input current is electrically insulated from the system by means of a current transformer. It
measures true RMS current value by means of fast sampling of the input current signals,
which makes it suitable for acquisition of transient events. A built-in microcontroller
calculates the measurands (current, frequency) from the measured signals. The measurands
can then be converted into load independent DC current or voltage which is proportional to
the true RMS measured value.
