Abstract
PURPOSE: To separate the current to a harmonic filter into a component from a line and another component from a thyristor converter and separately measure the components, by performing calculation.
CONSTITUTION: A harmonic component due to power distortion is separated from higher harmonics introduced into a filter and is determined by a vectorial measuring calculator VMC. The vectorial measurement of the harmonic current is effected after currents determined by current transformers SSCT, FILCT, THYCT and the output of a calculating transformer PT for measuring the voltage on a filter connection point are removed of the fundamental waves. The component due to the power distortion is thus separated from the higher harmonics introduced into the filter and is then determined.
