  • Page 24: Measuring Rcd Tripping Time

    Measuring loop impedance NO TRIP mode: To prevent tripping RCDs in the circuit: • Use the NO TRIP function for loop measurements. • An RCD with a nominal fault current of 15mA or above will trip. To measure L-PE loop impedance NO TRIP mode: 1.
  • Page 25 Tester indicates >50V Uf having been generated by the measurement. The measurement interruption caused by excess of Uf is only generated by the actual voltage present between the neutral conductor (N) and the protective earth (E). • Time-delayed residual current devices trip at nominal residual current within 130…500ms, for double nominal fault current within 60…200ms.
