Abstract
Apparatus and methodology are provided for measuring energy, particularly in a useful way for a multiphase system. Individual, like single-phase metrology blocks are provided to monitor energy in selected phases of a multiphase system. Individual data from a relatively upstream metrology block is passed to a relatively downstream metrology block, with the data stream being concatenated as the stream tracks from one metrology block to another. Energy data is coded as a predetermined small quantum of energy such that the last metrology block in a seriatim configuration of such metrology blocks may compute total energy consumption in the effective multiphase system by simple addition of the energy quantum data arriving at such last metrology block.

-
providing a plurality of energy monitoring devices, each of such energy monitoring devices comprising a first data combiner, a metrology board for generating energy related data, and a second data combiner;

21. Methodology for cascading data from single-phase metrology blocks to produce a multiphase metrology design, comprising the steps of:
-
providing a plurality of single-phase metrology blocks in a daisy-chain topology configured such that the first metrology block in the chain initiates a synchronization header to enable the synchronization of the next metrology block in the chain;
sending data downstream from a metrology block so as to include such metrology block'"'"'s own data concatenated with the data received from any previous metrology block, with energy measurements represented by the metrology blocks being encoded in discrete quantums of very small amounts of energy; and
using the last metrology block in the daisy-chain topology to compute the energy of all upstream metrology blocks, thereby producing an output used to obtain data representative of the polyphase energy, such that processing of the stream of data does not require arithmetic and logic units but rather only a basic adder to compute the multiphase energy. - View Dependent Claims (22)
