ABSTRACT:
A group metering method (and system) for monitoring electrical energy consumption by a plurality of proximate users replaces multiple individual user-meters by a single electronic meter. A single computational engine computes consumed energy values by the users and deploys a single subsection set (display, real time clock, and non-volatile memory) which can be located on a PCB. The system, usable for single or three phase, may be located out of reach from the users to make it tamper proof. Individual ADCs obtain electrical current values (through current transformers,) of power consumed by individual users and cooperate with a single DSP to compute energy consumption by individual users, readable on a common display in round robin fashion. Differences between the sum of energy values consumed by the users and a consolidated energy reading beyond a known threshold are reported as possible user-tampering. Asynchronous communication ports communicate with display units and AMR modules.
