METHOD FOR MONITORING ELECTRICAL POWER SUPPLY LINE COMPRISED IN SEISMIC CABLE, CORRESPONDING SYSTEM AND COMPUTER-READABLE STORAGE MEDIUM Russian patent published in 2018 - IPC G01V1/20 G01V1/38 G01V1/18 G01R31/08 G01R31/02 G01R15/24 

FIELD: measurement.

SUBSTANCE: invention relates to geophysics and can be used in seismic surveys. Disclosed is a method for monitoring an electrical power supply line comprised in a seismic cable and extending along the seismic cable, wherein the seismic cable further comprises: a plurality of seismic sensors arranged along the seismic cable, a plurality of controllers arranged along the seismic cable, an optical transmission line extending along the seismic cable for carrying data signals from or towards the controllers. Electrical power supply line supplies at least one pair of master and slave controllers. Master controller (C₁) of a given pair of master and slave controllers (C₁, C₂) performs a step of monitoring portion (250) of the electrical power supply line between master and slave controllers (C₁, C₂), by using an optical loop established on portion (240) of the optical transmission line between master and slave controllers (C₁, C₂), and starting from master controller (C₁) and passing through slave controller (C₂).

EFFECT: technical result is improving the accuracy of data.
