摘要： A device for testing the operation of a protection unit of an electrical network. The test device includes a generator for generating a pulse train in a secondary winding of a current transformer according to a profile of frequencies such that a measurement of the pulse train after passage through a low-pass filter is lower than a selected trip threshold, and a processing circuit arranged to identify a presence of the pulse train in a signal delivered by a second secondary winding of the current transformer. A protection unit including such a test device and to a method for testing an electrical protection unit.
