Abstract
The invention relates to an electrical power-supply network (1) on board a vehicle, the electrical power-supply network comprising: - an energy source (2); - distribution boxes (12, 13, 14) electrically connected to the energy source (2) and comprising electronic switching components (Cl1, Cl2, Cl3, C1, C2, C3, T4, T5, T6, Cn) upstream of electrical loads (A11, A12, E11, E12, L11, L12), the electrical power-supply network (1) comprising a monitoring member (122, 132, 142) for monitoring a measurement datum linked to the use of one of the electronic switching components (C1, C2, T4, T5, T6) located upstream of one of the electrical loads (A12, E12, L12), the measurement datum being distinct from a current or temperature measurement, the monitoring member (122, 132, 142) being able to cut off a supply of power to the electrical load (A12, E12, L12) as soon as the measurement datum is higher than a predetermined threshold.
