Advanced energy meters include features such as wide-range high-accuracy current measurement, fast digital calibration, protection against meter tampering and theft of service. Communication via Power-Line, RF or wired (Ethernet or RS485) are making the meters “smart”. Worldwide standards, like G3, PRIME, Meters&More, IEEE1901.2, and Wireless MBUS are supported by ST.  To fulfil those needs, ST has introduced a reference design platform for smart electronic power meters.
