Abstract :
The paper presents the testing methods, laboratory stand and devices used in tests of protection devices exchanging data through SDH network devices. The paper has arisen as a result of Institute of Power Engineering and PSE Operator cooperation. In this cooperation many tests were made. The range of tests covers the protection functionality tests and SDH devices test focused on determination of possibilities, conditions and problems that exist or may happen during their interoperation.
