Abstract

Винахід належить до вимірювальної техніки і може використовуватися для контролю якості електричної енергії, у релейному захисті електроустановок. Цифровий вимірювач квадратурних складових та коефіцієнтів несиметрії напруги за рахунок чотирнадцяти цифрових фільтрів із заданими амплітудно-частотними і фазочастотними характеристиками, шести суматорів, трьох блоків обчислення модулів напруги гармонічних сигналів та двох блоків ділення дозволяє підвищити точність вимірювання коефіцієнтів несиметрії напруги.The invention relates to measuring technology and can be used to control the quality of electrical energy in relay protection of electrical installations. The digital meter of quadrature components and coefficients of asymmetry of voltage due to fourteen digital filters with specified amplitude-frequency and phase-frequency characteristics, six adders, three blocks of calculation of modules of voltage of harmonic signals and two blocks of division allows to increase the precision of accuracy.
