Energy measuring and controlling method for local area network, involves storing measured data in memory, and attaching measuring devices i.e. energy meters, with each other, and monitoring apparatuses e.g. inverters,

摘要

The method involves measuring three different grids in a flow meter. A set of electric circuits is measured with two measuring stations. The measuring stations are connected with each other at an input unit. Measurement data and control of multiple apparatus such as inverters or current generators, are processed by a computing unit. The measured data is stored in a memory. A set of measuring devices i.e. electric meters, is attached with each other. The apparatuses are monitored, where the measurement data is processed and correlated. Independent claims are also included for the following: (1) an arrangement with one ternary numerator (2) a computer program product having a set of instructions for measuring and controlling current in local distribution networks.
