As for DC fuses, power capacity of the test device is heavily demanded in high current short-circuit tests, which constrains the development of high-breaking-capacity DC fuses. According to the characteristics of the DC fuses, three equivalent conditions are introduced: similar pre-arcing time, similar arcing energy, and similar recovery voltage. Meanwhile, two equivalent test methods are presented. The first method is to increase the resistance value of the direct test circuit, and the second method is to employ a bank of capacitors as the power source. By means of setting rational parameters for the proposed methods, a good equivalence to direct test and low cost can be obtained. Furthermore, the equivalence and its parameters setup of the proposed methods are discussed and illustrated. Finally, the proposed equivalent test methods and the direct test are compared through 110 kA short-circuit test, with DC fuses rated 1200 V/ 1250 A and 1200 V/ 200 A, which further verify the effectiveness of the proposed methods. The two equivalent test methods can be applied in short-circuit test of the DC current limiting circuit breakers.
