Experimental Analysis of Total Radiated Power by the Open Energy Meter 2G

الملخص EN

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.
