Abstract:
1. Method of conditioning mains for the purpose of rapid and electromagnetically compatible data transmission by way of current supply mains internal to a building, characterised in that a) an inductance having a high impedance for the carrier frequencies employed is introduced into the neutral conductor as close as possible to the building earth point, b) inductances are incorporated at the building service connection in two of the three phases L c) a short-circuit in terms of high-frequency of all four conductors relative to the building earth point is carried out on the building side at the building service connection, d) if one fault current circuitbreaker is present, the inductance is introduced into the neutral conductor on the load side of the fault current circuitbreaker and a high-frequency short-circuit is produced between earth conductor and the service connection terminal, which is at the building side, of the neutral conductor at the fault current circuitbreaker and e) if several fault current circuitbreakers are present the inductance is inserted on the side, which is remote from the building, of the fault current circuitbreaker as close as possible to the building earth point and the individual fault current circuitbreakers are bridged over in terms of high frequency at the neutral conductor terminals thereof.
