Claim 0:
1. A method for monitoring a polyphase electricity network, implemented at least partially in a processing unit of an item of electrical equipment connected to the polyphase electricity network, and comprising the steps, repeated regularly, of:
acquiring voltage measurements taken by voltage sensors (R1A, R1B, R2A, R2B, R3A, R3B) of the item of electrical equipment that are connected to the polyphase electricity network;
producing current values of electrical parameters from the voltage measurements;
accessing a reference table that comprises a list of connection configurations each associated with a distinct combination of reference values of said electrical parameters, the list of connection configurations comprising first connection configurations each corresponding to a distinct combination of connection or disconnection states for each phase (P1, P2, P3) and for the neutral (N);
implementing an exploratory algorithm intended to explore the reference table to identify the connection configuration associated with the current values of the electrical parameters.
