The company e-distribuzione S.p.A (the main Italian electricity distributor) has started in 2017 the massive installation of the second-generation smart electrical energy meters. These smart meters have several new features. In particular, the communication functions have been improved to enhance the reliability of the communication towards the concentrator: in addition to the traditional main PLC channel, a radio module has been added with a transmission around the frequency of 169 MHz. This paper assesses the characteristics of the emission due to this radio module, quantifying the total radiated power. The analyses were performed not only inside an anechoic room, to obtain repeatable results, but also in situations close to the normal operating conditions.

“…From a high-level viewpoint these interfaces can be classified as impacting on system operation and performance (i), on electrical safety (ii, iii), on functional safety (iii, v), on structural safety and impact on third parties (iv) and on electromagnetic compatibility (iii). Interfaces are then evaluated using more or less complex models fed among others by the rail electric parameters [20], including variability in a final compliance statement: validation of simulation models based on experimental data can be found in [21], where rail resistance and its variability are explicitly accounted for. Another example of tuning a model to fit experimental results is described in [22,23], where AC rail impedance is evaluated to predict network response to electric arc phenomena.…”

Running rails in electrified transportation systems are the interface element for several phenomena related to system performance, electromagnetic compatibility and safety: useful voltage at rolling stock, short circuit current, induced voltage, stray current, and track circuit operation. This work presents the physical and mathematical groundings of rail electrical parameters (dc and ac resistance, ac internal and external inductance) and experimental results available in the literature, discussing variability and reliability for each interface. The results consist thus of the identification of the relevant rails longitudinal electrical parameters, the presentation of a set of reliable experimental values, and the discussion of the best approach to manage their variability and uncertainty.

“…Literature shows that monitoring of dynamic and highly distorted signals for ac or dc high-current applications has been investigated earlier (see [4]- [7]). Nevertheless, no reference setup has been developed to provide traceability to international measurement standards for calibrations of the equipment used to measure such dynamic and distorted signals.…”

To assess the reliability of dc energy measurement equipment on-board trains, a setup was developed to characterize current transducers under realistic operating conditions. The operating principle is based on a current ratio measurement technique. The reference sensor is a high-precision zero-flux current transducer in combination with a broadband highprecision current shunt. The influence of ac distortion on this reference sensor was found to be within a few parts in 10 6 using an initial version of the setup, in which ac distortion was applied through a separate winding. A revised version of the setup employs a programmable electronic load to apply dynamic currents up to 600 A. The setup was used to characterize a 100 μ high-current shunt resistor. The effect of dissipative heating on the dc transresistance error was around 0.03 %, with a settling time of about half an hour. The short-term intrinsic current dependence was also around 0.03 %. The effect of ac distortion was within a few parts in 10 6 . The intrinsic current dependence and the onset of the heating effect were also observed when exposing the sensor to a dynamic current profile that was recorded during a trip between two successive underground train stations on Metro de Madrid. These results demonstrate that the setup described in this paper is very effective for characterizing dc current sensors for practical railway applications. Future work will concentrate on even more demanding current signals, such as chopped signals, and on other types of sensors and measurement systems.
