摘要： An arrangement for use in a utility meter includes at least one circuit path, a three phase service switch, and a three phase monitoring unit. The at least one circuit path operably couples a source of electrical energy to a load. The service switch is operably coupled to the at least one circuit path and is configurable in an open state and a closed state. The monitoring unit is operably coupled to the at least one circuit path between the load and the service switch and is configured to detect a presence and an absence of line voltage on the load. The monitoring unit is further configured (i) to generate an open circuit signal responsive to the detection of the absence of line voltage on the load, and (ii) to generate a closed circuit signal responsive to the detection of the presence of line voltage on the load.

摘要： 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.

摘要： An arrangement for use in a utility meter includes a sensor and a processing circuit supported by a base of the meter, and a magnetic element carried by the cover of the meter, in which the cover is removably mounted to the base. The sensor includes at least two magnetizable elements, such as inductors, that are magnetized at opposite polarities when the meter is closed and operable. The magnetizable elements are positioned in very close proximity so that as cover is removed the magnetic element passes the elements to cause the magnetizable elements to assume the same polarity. The processing circuit continuously polls the magnetizable elements to evaluate their respective polarities and is configured to issue a tamper indication when the detected polarities are the same.
