This transducer is used for measurement
of Active Power for single phase (STE-A-3T)
system as well as for 3-phase, 3-wire (STE-B-3T)
system and 3-phase 4-wire (STE-C-3T) systems
with balance and unbalanced load. They are
suitable for measurement of both import
and export of power. The output is a load
independent DC current or voltage which
is proportional to input power. The output
can be connected directly to indicating
instruments or to data transmission system.
