FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry, to investigation or inspection of wells, is intended for receiving and transmitting information and electric energy to actuators and mechanisms during operation of wells for extraction of fluid. In the process of implementing the method, the state of connection of each of the telemetric modules is determined by measuring voltage on the line for transmitting information and electric energy between the ground and submersible units through an analogue-to-digital converter and, in case of exceeding the specified value, which indicates disconnection of one of the telemetric modules, includes switches with additional resistors installed in the ground unit. Telemetry modules do not interact with each other and are installed in separate sealed bodies making the submersible unit. Ground unit contains low-pass filter. Submersible unit additionally comprises voltage filters.
EFFECT: invention provides higher reliability of the system for obtaining telemetric information while providing sufficient reliability of measurement results.
