Disclosed are apparatus and methodology subject matters for providing improved functionality of a meter in a 2-way communications arrangement, such as an Advanced Metering System (AMS) or Infrastructure (AMI). More particularly, the present technology relates to methodologies and apparatus for providing load side voltage sensing for utility meters which preferably are operable with remote disconnect features in an Advanced Metering Infrastructure (AMI) open operational framework. The present subject matter provides enhanced capabilities resulting in improved functionality, increased safety, and greater economy vis-à-vis fraud detection for individual metrology components in an open operational framework. Meters per the present subject matter utilize a detection circuit, which is situated generally downstream of a remote disconnect functionality. Such detection circuit is able to sense whether voltage exists or doesn't exist at such relatively downstream, or load side location. Providing such functionality allows for: (a) verification that a remote disconnect switch did open subsequent to an instruction or command to do so, (b) identification of possible user fraud, as would possibly be reflected by the presence of voltage at a time when the remote disconnect switch is open, (c) verification that the remote disconnect switch did re-close after having been given an instruction or command to close, and (d) verification of lack of voltage present before re-closing such remote disconnect switch, which serves an important safety feature.

What is claimed is: 1. An electricity meter for use within an advanced metering system having and operating relative to a network, other meters, user interfaces, and central collection functionality, comprising:a line side which receives electrical service when connected to said meter;a load side, downstream from said meter line side, which electrically connects with an electrical load when connected to said meter;a detection circuit, upstream from said meter load side and downstream from said meter line side, for detecting the presence of electricity at said meter load side;a remote disconnect switch, upstream from said detection circuit and downstream from said meter line side, controllably actuated for electrically connecting and disconnecting said meter line side relative to said meter load side, so that electrical service when present at said meter line side is, respectively, electrically connected with, and disconnected from, an electrical load when present at said meter load side;metrology, downstream from said meter line side and upstream from said meter load side, for monitoring the consumption or production of electricity vis-à-vis electrical service and electrical load associated with said meter; anda bidirectional communications link, linking said meter and a network operating relative to an advanced metering system, such that data may be communicated regarding actuation of said remote disconnect switch and presence of electricity at said meter load side;wherein said detection circuit comprises a voltage sensor electrically in parallel with said meter load side; said detection circuit comprising a filtering capacitor, an over-current protection resistor, an opto-isolator, and a transient voltage suppressor for setting the turn-on voltage of said voltage sensor.
