Abstract
A device for detecting a fault of at least one street lamp of a plurality of street lamps which are connectable in common to an AC power supply is proposed. The proposed device allows detecting whether a fault has occurred based on obtaining measures representative of the total active and reactive power supplied by the AC power supply to the plurality of street lamps, and detecting variations in these measures. Optionally, also the type of fault can be determined based on detected variations in the power measures.
