Power Line Transducers

/> </div> <div class=
DESCRIPTION

AE transducers convert various electrical power line parameters viz. Voltage, Current, Frequency, Power Factor, Active power, Reactive power, Apparent power into load independent DC current or voltage output. These are used in various electrical, thermal, chemical & other power plants to monitor processed data either locally or remotely, using various devices such as indicating meters, data loggers, recorders, SCADA systems.
