Abstract
An electricity meter includes a sensor circuit, a measurement circuit, a leading PF detection circuit and a control circuit. The sensor circuit is operably connected to detect voltage and current provided to a load, and generates corresponding voltage and current measurement signals. The measurement circuit is configured to generate energy consumption information based on the voltage and current measurement signals. The leading PF detection circuit is configured to generate a first value representative of a phase difference of the current measurement signal with respect to the voltage measurement signal, and to generate a leading PF detection signal responsive to determining that the first value corresponds to a leading power factor that leads unity power factor by more than a predetermined threshold. The control circuit stores an indication in memory responsive at least in part to the leading PF detection signal.
