<p>The invention relates to a circuit arrangement for measurement transmission of DC voltages and/or direct currents from a live measurement-voltage source to a test set. In the case of such a circuit arrangement, the measurement-voltage transmitter and the test set are intended to be isolated from one another in potential terms. To this end, the invention provides that in each case one transmission device, which contains a voltage/frequency converter, a potential isolating device and a frequency/voltage converter, is arranged between the measurement-voltage source and the test set which is connected to reference potential. The circuit arrangement can be used, especially in the case of devices for removed power supply, for central indication of a plurality of measurements (readings). <IMAGE></p> |
