    Abstract: Protection unit (1) for an electrical distribution network has a programmable logic unit (13) for execution of protection functions. The protection unit initiates switching of a primary switch (2) dependent on the processing of values measured by current and voltage meters (3, 4). An Independent claim is made for a method for installation of protection function software in a programmable logic unit of a protection unit which has the following steps: transfer of a hardware design for the communication function over a communications network (5); programming of the PLU according to the description and; execution of the protection function by the programmable logic unit.

    Abstract: The transmission method involves using interleaving of the data blocks to be transmitted at the transmission side. Coded sub symbol sequences are provided used for modulation of a carrier frequency, with corresponding demodulation and de-interleaving at the reception end. A multi-carrier modulation method is employed for modulation of several channels via parallel sub symbol streams, obtained from the serial data stream to be transmitted.
