DATA TRANSMISSION AND POWER SUPPLY SYSTEM FOR WELL APPLICATION Russian patent published in 2008 - IPC H04B3/54

Abstract RU 2325032 C1

FIELD: data transmitting.

SUBSTANCE: within this system well assembly is connected by AC to wires of power supply cable through star-connection point of motor-generating assembly ESP. Ground assembly is connected by AC to wires of power supply cable. Ascend telemetric data is transmitted through connection chart by AC, supported by well assembly and ground assembly. Descent command data of remote control is transmitted through another communication chart by AC, supported by ground assembly and well assembly. These communication charts by AC imply independent power supply to well equipment. All communication between ground and well equipment is performed by power supply cable without any auxiliary communication lines. Data transmission is carried out in case of short-circuit to ground in power supply cable.

EFFECT: cost-effective high-speed data transmission system tolerable to short circuit.
