Abstract

Microelectronic technologies made possible the implementation of solid state based metering systems. In this paper, an ASIC design that implements all but the analog part of a watt-hour meter is described. This ASIC designed with the APBB technology is intended to be used in conjunction with the Ferraris power meter in a hybrid telecounting system or in a fully static watt-hour meter. In the first case, the data received and processed by the ASIC is the disk turn count of the Ferraris power meter, being the transmission from the latter to the ASIC achieved by optical interconnection. In this second case, a fully static power meter is used, and, data received by the ASIC are two 12 bit words representing the current and the voltage values
