Powerline communication apparatus used in low voltage installations – Radio disturbance characteristics – Limits and methods of measurement – Part 5: Powerline communications (PLC) used on alternate current (AC) connection of equipment intended for control of Photo-Voltaic sites
This part of EN 50561 applies to equipment using powerline communication technology and intended to be installed in industrial PV sites.
The document specifies limits and methods of measurement of radio disturbance characteristics for equipment that communicates over the AC low voltage power lines in the frequency range 0,5 MHz to 12 MHz, and that utilises a signal path between phase to phase or phase to neutral.
Procedures are given for the measurement of signals generated by the equipment and limits are specified within the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limit is specified.
NOTE The requirements defined in this standard effectively restrict the intended power line transmission frequencies to below 12 MHz
The requirements defined in this standard are for PLC functions of the equipment. For functions other than PLC, the requirements given in other applicable product standards shall be applied.
The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio-transmitter as defined by the ITU, nor to any spurious emissions emitted by the radio-transmitter. Specific requirements for the radio function, if any, can be found in the ETSI 301489 series of standards.
