Power Current Transducer

Measures motor power and current in order to determine overall system effeciency.


The power-current transducer is used for measurement of motor power and current. The amount of power that the motor uses can be measured and compared to the amount of theoretical power required to lift liquid from the net liquid level depth (obtained from an acoustic liquid level test) to determine an overall system efficiency. This is very important for determining wells that are candidates for improved operation. A conventional beam pumped well should have an overall electrical efficiency of approximately 50%. Wells operating at low efficiencies can be further analyzed to determine the proper procedure to improve operations.

The power-current transducer consists of three voltage probes that are attached to the three wires to the motor. Two current transducers are installed around two of the three wires that power the motor. The power-current transducer assembly is compact and has approximate dimensions of 8" x 12" x 8". Wires do not need to be removed or changed in any way to install the power-current transducer.
