Abstract
High-phase-order transmission is considered as a viable alternative for increasing the power transmission capability of a transmission line. Fault analysis is an important aspect of the determination of breaker and protection specifications. General expressions for the fault currents and voltages for various types of ungrounded (isolated) faults are derived for any N-phase system. Actual calculations for six- and twelve-phase systems are made, and the results are presented as normalized graphs.<>
