A comprehensive procedure for the analysis of fault currents in power rectifiers has been developed and some of the more usual cases have been analyzed for the 6-phase double-Y circuit. However, further analyses are still required to cover all the conditions which may be encountered in practice and provide a ready means for determining fault currents.

Fault-Current Measuring Device
Transactions of the American Institute of Electrical Engineers, 1946IN electric power system operation numerous problems are encountered in analyzing the results of short circuits and in the physical location of the trouble. Some devices now available for analyzing short circuits in a-c circuits are the oscillograph, the annunciator ammeter, and a magnetic link device requiring rectifiers.

Abstract To mitigate the threat from increasing fault current level in high-voltage transmission systems, a “dredging theory” based on the fault current splitter (FCS) was proposed to help the over-duty circuit breaker clear the fault. However, detailed practice of this theory is not fully studied.

Dual-Functional Dynamic Voltage Restorer to Limit Fault Current
IEEE transactions on industrial electronics (1982. Print), 2019This paper proposes a dual-function dynamic voltage restorer (DFDVR) with fault current-limiting capability. The new topology can operate under different modes: the short-circuit fault current-limiting mode and the compensation mode for voltage ...
