Abstract
A method for automatically propagating a voltage along a marine seismic streamer, the method including detecting, at an ith concentrator of the streamer, a first voltage applied at a first high-voltage rail HV; detecting, at the ith concentrator of the streamer, a second voltage applied at a second high-voltage rail HV, the first and second high-voltage rails extend over the entire streamer; checking a predetermined condition at a first local controller of the ith concentrator; and closing a first switch SW, which propagates the first high-voltage rail HV, when the predetermined condition is satisfied.
