<p>The method involves detecting a reactive current flowing in side of the loads, by a special electrical or electronic circuit such as a terminator (70), during current flow disruption by a transmitter/modulator. The reactive current portions in an energy supply line are derived before the portions put back a long distance over the line. A real power keying results in a region of minimum instantaneous value of the real power of loads. Independent claims are also included for the following: (A) a device for data communication in an AC voltage system (B) a use of a device for data communication in an AC voltage system</p> |
