An Electric Submersible Pump (ESP) artificial lifting downhole sensor data transmission may fail due to a reduced ESP electric cable isolation. An electronic recovering system prototype is proposed to re-establish the lost sensor signal due to the electrical current leakage that flows from the conductors to the ground. An innovative electronic system prototype has been developed to monitor an ESP downhole sensor operation and recover its lost signal due to the current leakage is proposed. Experimental tests are discussed, simulating high current leakage, and the transmission data recovered by the prototype are compared with data from a conventional oil industry downhole sensor.
