It is proposed a method for monitoring an electrical power supply line comprised in a seismic cable and extending along the seismic cable, the seismic cable further comprising: 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, the electrical power supply line supplying at least one pair of master and slave controllers. The master controller (C1) of a given pair of master and slave controllers (C1, C2) performs a step of monitoring a portion (250) of the electrical power supply line comprised between the master and slave controllers (C1, C2), by using an optical loop established on a portion (240) of the optical transmission line comprised between the master and slave controllers (C1, C2), and starting from the master controller (C1) and passing through the slave controller (C2). |
