Abstract
A method of estimating a periodic voltage, such as an input voltage, of one of the phases of an electrical circuit with at least two phases including a voltage sensor for each of its phases, each voltage sensor being capable of outputting a signal representative of at least a part of period of the periodic voltage of the phase. The method including the following steps: measure the representative signal starting from the voltage sensor; amplify the representative signal by a gain determined in the absence of an electrical fault in the circuit and based on a reference voltage common to all phases in the electrical circuit (); use the amplified representative signal to estimate the periodic voltage. A device for estimating a voltage and an electrical circuit including such a device.
