ISN 50561-1, ISN for PLC measurement, acc. EN 50561-1Description ISN 50561-1 is an impedance stabilization network (ISN) for measurements of asymmetrical disturbance voltage of power line communication equipment. This ISN is built according to the standard EN 50561-1, Annex B, Figure B.1. An impedance stabilization network has the following purposes:
The measurement setup to obtain the conducted asymmetrical disturbance voltage is explained in the standard EN 50561-1, chapter 9.4. Figure 6 shows the setup. To minimize the chance of measurement errors the additional possibilities to ground the ISN 50561-1 may be used. Normally it should be sufficient to put the not-painted bottom of the ISN on the reference ground plane. If a vertical measurement setup is required, the ISN can be mounted at the bracket located at the bottom using four M6 screws.
