INCREASE THE ACCURACY OF ENERGY ACCOUNTING AND CONTROL USING A MEASURING SYSTEM

摘要

The invention relates to instrumentation technique, as well as to electric engineering, in particular to interaction of measuring current transformers (TC) and measuring voltage transformers TV. A method for accuracy increase of energy accounting and control using a measuring system allows increasing true accuracy of the whole measuring system in accordance with a certificate and protocol of state metrological certification for voltage, current transformers and electric meters. This allows decreasing measurement accuracy of total energy measuring relative to accuracy which depends only on accuracy of an electric meter.
