<p>The method involves modulating communication signals through transformers on at least one signal conductor (11; R', S', T'), which does not carry any current during normal operation, and which is electrically isolated against at least one adjacent current or adjacent phase conductor (12; R, S, T). These communication signals are simultaneously decoupled from a ground potential. The communication signals are separated from the ground potential in at least one intermediate station (2, 3) with respect to a high frequency (HF) component, and without coupling and/or decoupling. The intermediate station comprises at least one switch (S2, S3) in the current or phase conductor.</p> |
