“…Finally the temperature sensor is a diode with a constant current forward bias in a special circuitry. For extended linearity we used 2 diodes, as the 1N4148, one as an ambient reference and the other in physical contact with The simple sensors, that we have developed, tested, and presented in a previous paper [12], utilized sophisticated electronics, in order to maintain the linearity and accuracy. With these sensors we can make linearly measurements of the appropriate GICs values and after the necessary filtering and amplification, we can send the linear voltage output to an optoelectronic pulse repetition rate converter, that optically drives the transmitter's modulator, as in Fig.4.…”

We developed and installed telemetry, of the induced effects, to an electrical network, from geomagnetic storms, using field & temperature sensors spread out in the electrical power network, near to the recording centre, communicating reliably, through the power lines. The telemetry's transceivers communicate in the regulated D-band (140-148.5 KHz), with a Pulse Position Modulation code type, in order to avoid collisions and minimizing the interference and noise, that may be obstacle the real time sensing-observing system of the electric & magnetic Extreme Low Frequencies (ELF) fields and of the transformers/ambient temperature difference as well. In the collection centre we add the option of compare the measured values with the standards & limits (Harmonics, Electro-Magnetic Compatibility, Transformers temperature). In our paper we include the dominant information of the specialized sensors and transceivers that we developed, and of the measurement-recording unit, accompanied by the results of the main impact parameters, during a geomagnetic storm, from laboratory applications of this type telemetry. The final conclusion is that we develop a reliably and small cost sensing telemetry, over the power networks, for the induced impacts from geomagnetic storms.
