| 摘要 |
The invention relates to a detection device (D) for mounting in an electrical connector system (CV) coupled to a power supply network (RA) comprising an earth line (LT), and at least one phase line (LP) and a neutral line (LN) having a main voltage differential (VO). Said electrical connector system (CV) comprises first (L1) and second (L2) lines coupled respectively to the neutral (LN) and phase (LP) lines, or vice versa, and a third line (L3) coupled to the earth line (LT). Said device (D) comprises: i) first measuring means (M1) connected between the first (L1) and third (L3) lines, coupled by a first impedance (Z1), in order to measure a first voltage differential (V1) between said lines, and/or ii) second measuring means (M2) connected between the second (L2) and third (L3) lines, coupled by a second impedance (Z2), in order to measure a second voltage differential (V2) between said lines, and iii) processing means arranged in such a way as to determine whether at least one of said first (V1) and second (V2) voltage differentials belongs to a corresponding range of values and, if not, to generate a warning signal signalling an earth line (LT) connection fault. |
