Abstract
This part of EN 50561 specifies limits and methods of measurement of radio disturbance characteristics for in-home PLC communication apparatus that use the low-voltage power installation as the transmission medium by intentionally injecting a signal EXCLUSIVELY between two Phase (L) conductors or between one Phase (L) and Neutral (N) conductors of the low-voltage power installation.
NOTE 1 This part of EN 50561 does NOT apply to in-home PLC communication apparatus that use the low-voltage power installation as the transmission medium by intentionally injecting a signal between any Phase (L) or Neutral (N) conductors and the ground or earth (E) conductor of the low-voltage power installation.
This part of EN 50561 applies to equipment that communicate over this medium in the frequency range 1,606 5 MHz to 30 MHz.
NOTE 2 Similar equipment that communicate outside this frequency range is under study and will be covered by another European Standard.
Procedures are given for the measurement of signals generated by the equipment and limits are specified for the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limit is specified.
