FIELD: electrical engineering.
SUBSTANCE: invention relates to testing electrical devices in power electronics. Thyristor valve testing system based on interaction of logic functions of the software, wherein the testing system comprises: a test thyristor valve (5), VBE (3) and testing device (4), and VBE (3) has a special testing mode, wherein testing device (4) provides three steps for each testing element. Test thyristor valve (5) and VBE (3) are connected by optical fibres (1), and the tested thyristor valve (5), and testing device (4) are connected by means of cables (2), and the connection between VBE (3) and testing device (4) is absent.
EFFECT: high reliability of the system due to the fact that all tests and testing requirements can be performed by interaction at the logic function level between the VBE and the testing device without introducing and removing the connected fibres in the field of operation.
