Shown on this slide is a simple description of the single phase meter. The multiple measurements capability includes active, reactive, apparent energy, and frequency with Vrms and Irms as well, with multiple sensor support from a current transformer, from an inexpensive shunt implementation to the complex Rogowsky coil. The STPMxx supports this sensor capability, with different accuracy levels and with different implementations. It also provides 0.1% accuracy over the 1:1000 range and short self-calibration that gives the chip the capability to shorten the time to market and the time to volume for any implementation. Anti-tamper protection is embedded, and ST complies with the standards from EM and ANSI and IEC.
