Measurement value transmission method using radio signals

摘要

The method involves transmitting electrical measurement values using radio signals. Preferably, current and voltage transformer are used which have an integrated transmitter in the housing. When several transmissions are carried out within a defined range, the transmission frequencies can be chosen that the frequencies do not influence each other. The energy for the operation of the transmitter can be gained from the measurement circuit. The energy necessary for the operation of the transmitter may be supplied from outside.
