TL;DR: In this paper, an apparatus and method for measuring the consumption of electricity from a mains supply which is either single or multi-phase is described, which can detect when tampering with connections to the supply occurs as for instance, may be done in an attempt to reduce the quantity of energy registered as having been used.
Abstract: An apparatus and method is disclosed for measuring the consumption of electricity from a mains supply which is either single or multi-phase. The apparatus and method of the invention is also able to detect when tampering with connections to the supply occurs as for instance, may be done in an attempt to reduce the quantity of energy registered as having been used. In a meter which takes as inputs signals indicative of the voltage and currents present in the supply a tamper is registered whenever the voltage reading, for instance in one phase of the three-phase supply, is absent while the corresponding current is present. If both voltage and current are absent this is not registered as tampering but may be noted as a fault in the system.

TL;DR: In this article, an electronic electric meter for use in a networked automatic meter reading environment is presented, which includes a meter microcontroller, a measurement microcontroller and a communication microcontroller.
Abstract: An electronic electric meter for use in a networked automatic meter reading environment. The meter includes a meter microcontroller, a measurement microcontroller, a communication microcontroller and spread spectrum processor, and a plurality of other communication interface modules for communicating commodity utilization and power quality data to a utility. The meter measures electricity usage and monitors power quality parameters for transmission to the utility over a spread spectrum local area network (LAN) to a remotely located gateway node. The gateway node transmits this data to the utility over a commercially available fixed wide area network (WAN). The meter also provides direct communication to the utility over a commercially available network interface that plugs into the meter's backplane or bus system, bypassing the local area network communication link and gateway node.
