A method of measuring negative-phase-sequence currents in a three-phase system
A method of measuring the negative-sequence current in an unbalanced three-phase circuit. A four-winding current transformer, in conjunction with a phase shift network and an alternating current ammeter, was used for obtaining a current proportional to, and in phase with, the negative-sequence …

Transmission grid strength analysis and operation of inverter-based microgrids
… the motor load. However, the magnitude of the negative-sequence current an inverter can supply is limited by its relatively low rated current. Therefore, we investigate the range of negative-sequence current the inverter can supply and derive formulas to determine the minimum capacity required …

Correcting Current Imbalances in Three-Phase Four-Wire Distribution Systems
… system. Through this redistribution, negative- and zero-sequence currents are eliminated and a balanced system is seen upstream from the point of installation.</p> <p>The UCSC consists of three separate single-phase H-bridge inverters that all share the same dc-link capacitor. Each of …
