5. 2 Coupling of the intermediate pulse Because of the low frequency content of the intermediate pulse neither capacitive nor inductive coupling is possible This is due to the very high capacitance inductance required for the coupling efficiency In addition these very high capacitance inductance will drain high current from the device or from the source connected to the line under test Therefore the methods of coupling will be the following e On shielded cables direct connection to the generator e Onmains AC DC supply connections direct coupling to the pulse generator The mains source or the auxiliary test equipment must be powered through an isolating transformer in order to force the current of the pulse to flow in the protective device In this way the external load is isolated The intermediate pulse generator will be equipped with 4 independent outputs which will allow the coupling on 4 lines The pulse will be injected on 1 wire to ground or 2 3 or 4 lines common mode e On signal data telecom cables 1 A 4 wires 60 Vac 1 A Like already explained above capacitive inductive coupling cannot be used therefore a direct coupling will be carried out through the 4 outputs of the generator A transformer could also be used to isolate the connected equipment from the external world Summary we recommend to use direct coupling No specific coupling device is proposed Eventually a A 60 A 230 Vac isolating transforme
