摘要： PROBLEM TO BE SOLVED: To provide an improved device and a method for calculating an amount of energy consumption on the whole stages in a multiphase system, using one or a plurality of single phase measuring blocks.
SOLUTION: Upon sending each data from a certain measuring block located relatively on the upstream side to a certain measuring block located relatively on the downstream side, a data stream is connected so as to track a stream from one measuring block to the other measuring block. Energy data is coded as a designated small amount of energy, and the final measuring block in a successive structure of these measuring blocks simply calculates the amount of total energy consumption in an effective multiphase system, by adding energy quantum data reaching to the final measuring block.

摘要： A power supply system and corresponding methodology is provided for providing a self-protected power supply for use with electronic electricity meters. The self-protecting features are provided, in part, through the use of surface mounted resistive components corresponding to a resistor dropper portion of the power supply. The use of surface mount components also provides a general reduction in circuit board surface area requirements thereby providing a compact overall construction and provides economies with respect to reduction in manufacturing process steps. When the surface mount resistor divider is configured along with a half-wave rectifier, a low voltage DC supply is obtained from a direct connection to a much higher voltage AC mains source without requiring the use of coupling capacitors or transformers. Plural output voltages may be provided and capacitive filtering may be associated with the outputs. The use of a surface mount resistor divider in combination with surge protection elements helps to distribute any power surge over the power supply, which facilitates the use of less robust surge protection devices to achieve desired levels of protection.

摘要： 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.
