Description
The model GW5 Watt transducer
provides power measurements
to within ±0.2% of reading
accuracy in single- or polyphase
systems. The Model GV5 VAR transducer
provides reactive power measurements
to within ±0.2% of reading
accuracy in single- or polyphase
systems. The electrically-isolated
dc output is proportional to
the instantaneous power averaged
over several cycles.
Currents
up to 20A and voltages up to
600Vac can be directly connected
to the GW5 and GV5, thus eliminating
the additional cost and additive
errors of current and voltage
transformers for these ranges.
The GW5 and GV5 can be used
with OSI metering class current
transformers for measurements
up to 10 kiloamperes.
Specific
outputs can be selected to interface
with any data acquisition system
from a simple recorder to a
computer-, SCADA-, or PLC-based
system.
The
GW5 is widely used in a variety
of applications, including hydroelectric
generator output measurement,
end-of-line appliance testing
for energy consumption, building
automation, energy management,
and cogeneration systems.
