Claim 2:
3. The monitoring method according to claim 2, wherein the implementation of the exploratory algorithm comprises the steps of:
testing a connection configuration, by checking whether predetermined criteria associated with said connection configuration are fulfilled, the predetermined criteria being defined based on the electrical parameters;
if the predetermined criteria are fulfilled, deducing therefrom that said connection configuration is that which corresponds to the current values of the electrical parameters,
if not, repeating the testing step with another connection configuration,
wherein the electrical parameters comprise:
measured line-to-neutral voltages, each measured line-to-neutral voltage being representative of an amplitude of a line-to-neutral voltage ({right arrow over (V′1)}, {right arrow over (V′2)}, {right arrow over (V′3)}) between one of the phases and the neutral; and/or
measured line-to-line voltages, each measured line-to-line voltage being representative of an amplitude of a line-to-line voltage ({right arrow over (U′1)}, {right arrow over (U′2)}, {right arrow over (U′3)})) between two distinct phases; and/or
measured angles (Phi1, Phi2, Phi3), each measured angle being equal to an angle between a vector representation of a line-to-neutral voltage between one phase and the neutral, and a vector representation of a line-to-neutral voltage between another phase and the neutral,
wherein the exploratory algorithm implemented is a second exploratory algorithm that only uses the measured line-to-neutral voltages and the measured angles as electrical parameters,
wherein the predetermined criteria, associated with the following connection configurations, only comprise comparisons between the measured angles and angular thresholds:
the neutral and all the phases are normally connected;
the neutral is inverted with one of the phases;
the neutral is disconnected and all the phases are connected.
