Abstract

A method (200) of determining a functionality state of an electric power supply to one or more of a plurality of electric conductors (C1 - C6) in an electric circuitry (E) comprises receiving (205), by means of a control unit (110) of an electric monitoring system (100), at least one peripheral voltage signal from at least one peripheral voltage sensor (122-1 - 122-6), the at least one peripheral voltage signal indicative of a voltage in an electric conductor (C1 - C6) of a plurality of electric conductors of an electric circuitry (E). The method (200) further comprises receiving (210), by means of the control unit (110), a supply voltage signal from at least one supply voltage sensor (116-1 - 116-3), the supply voltage signal indicative of a voltage of a supply line (S) which the electric conductor (C1 - C6) is configured to be connected to in the electric circuitry (E); determining (220), by means of the control unit (110) and based on the received peripheral voltage signal and the received supply voltage signal, a voltage amount difference (ΔA) between a voltage amount of the voltage in the electric conductor (C1 - C6) and a voltage amount of the voltage of the supply line (S); comparing (225), by means of the control unit (110), the voltage amount difference (ΔA) with a threshold voltage amount difference (T1); and, when the comparing (225) of the voltage amount difference (ΔA) with the threshold voltage amount difference (T1) yields that the voltage amount difference (ΔA) exceeds the threshold voltage amount difference (T1), determining (230), by means of the control unit (110), that an electric connection between the electric conductor (C1 - C6) and the supply line (S) is in a dysfunctional state. The method (200) further comprises, when the comparing (225) of the voltage amount difference (ΔA) with the threshold voltage amount difference (T1) yields that the voltage amount difference (ΔA) does not exceed the threshold voltage amount difference (T1): determining (235), by means of the control unit (110) and based on the received peripheral voltage signal and the received supply voltage signal, a phase angle difference (ΔP) between a phase angle of the voltage in the electric conductor (C1 - C6) and a phase angle of the voltage of the supply line (S); comparing (240), by means of the control unit (110), the phase angle difference (ΔP) with a threshold phase angle difference (T2), and, when the comparing (240) of the phase angle difference (ΔP) with the threshold phase angle difference (T2) yields that the phase angle difference (ΔP) does not exceed the threshold phase angle difference (T2), determining (245), by means of the control unit (110), that an electric connection between the electric conductor (C1 - C6) and the supply line (S) is in a functional state.
