摘要

It consists of means 4 of converting the decimal reading of the meter 1 into digital form, means 5 of selecting and converting the decimal number of the subscriber into digital form, meters for voltage and current strength 7, 33, 34 present in the line 11, means 6, 35, 36 of cutting off the supply to the subscriber in event of overload and means of sending 10e the data and receiving 10r instructions, all of this governed by microprocessor 8 assisted by a discriminator-memoriser 9. Said data and instructions are sent and received in high-frequency signals to and from the transforming station ET, equipped with a data receiver 19r and instruction sender 19e, connected to the microprocessor 20, interface 21 and modem 22, and finally being sent and/or received at the modem 23 and microprocessor 24 of the company CE.
