摘要
A single-phase electric meter having a phase conductor intended to be connected to a phase of an electric line located upstream of the single-phase electric meter and to a phase of an electric installation located downstream of the single-phase electric meter, the single-phase electric meter further including a breaking unit mounted on the phase conductor, an upstream voltage sensor arranged to periodically measure an upstream voltage upstream of the breaking unit, and a processing device arranged to acquire upstream voltage measurements and to open the breaking unit when the upstream voltage drops below a first predetermined threshold voltage.
