Load test on superconducting transformer and fault current limiting devices for electric power system
- Saga Univ. (Japan)
A superconducting fault current limiting transformer has been investigated to find out its feasibility. In general, the following two types of superconducting fault-current limiters could be expected: non-inductive two-port and four-port devices based on superconductive-to-normal state transition. The authors have investigated the transient phenomena in the transformer and then designed a 10 kVA superconducting fault current limiting transformer. First of all, in order to understand performances during quenching in the main coils of the transformer at power system faults, no-load and short-circuit tests in the auxiliary coils were performed. With the same test for the main coils and four windings, exciting conductance, susceptance and leakage impedance were estimated. Under a constant resistive tests were carried out. Test results are presented.
