Abstract

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 methodologies and apparatus for providing load side voltage sensing for utility meters which preferably are operable with remote disconnect features in an Advanced Metenng Infrastructure (AMI) open operational framework The present subject matter provides enhanced capabilities resulting in improved functionality, increased safety, and greater economy vis-a-vis fraud detection for individua 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.
