1.  The Invention
	Title: Equipment for testing circuit breakers The problem the inventor(s) wanted to solve: To enable precise and fast testing thermal triggers for circuit breakers. Description. The novelty in these test stands is: a power electronic source of sinusoidal current; a programmable microprocessor – aided system controlling the process of tests; automatic recording of results and a computer controlled thermal chamber. Source of sinusoidal current provides smooth amplitude control within 1:3000, which permits a wide range of the apparatus to be tested. Testing 36 power chains is possible at the same time. Presentation: Poster Advantages The possibility of testing, at the same test stand, circuit breakers with different rated currents; power electronic sources of sinusoidal current with controlled amplitudes, with an error <1%; recording and archivization of test results; automatic realization of tests, withhout operators (with operator's participation limited only to installing the apparatus and putting the test stand into operation; visualization of the test progress; a current circuit resistant to short-circuits and breaks. Stage of development. Production item. Documentation available: Yes   leaflet, brochure.
