<p>A test circuit for a direct current circuit breaker, characterised in that it comprises at least one voltage source (2), at least one re-arming device (3), an inductor (6) with, in parallel, a short-circuiting means (7), in series with the voltage source, and a connection point capable of being connected to a direct current circuit breaker to be tested (1), and in that it is capable of providing the direct current circuit breaker with a current having a first value corresponding to that of a normal operating current, followed by a second value higher than the first, corresponding to that of an overcurrent.</p> |
