Abstract
A meter including a phase conductor connected to a phase line of the network, a cut-off member, and a detection circuit comprising: an injection chain arranged, while the cut-off member is open, to generate a test signal with a predetermined voltage level, and arranged to inject the test signal into the phase conductor downstream from the cut-off member; a measurement chain arranged to measure an intermediate voltage level of the test signal at a measurement point of the injection chain, which point is situated between the generator component and the injection component; a processor component arranged to act as a function of the intermediate voltage level in order to determine whether the circuit breaker is open or closed.
