A 1-50 megahertz high frequency current transformer made from a PLA composite that predicts when an electric submersible pump system will fail. high frequency current transformer generates a 4-20 milliamp signal that indicates when the electric submersible pump system will fail.

High frequency transformer for predicting failure of an electrical submersible pump system

A common mode line-to-ground filter is disclosed which includes but is not limited to a resistor, capacitor and a ground. The common mode line to ground filter is connected on a high side of a step-up transformer. A low side of the step-up transformer is connected to a variable frequency drive that provides a semi-sinusoidal voltage waveform. The common mode line to ground filter generates a filtered sinusoidal waveform from the output of the step-up transformer. The filtered sinusoidal voltage waveform is supplied via an electrical cable to an electrically submersible pump deployed downhole.
