Abstract :
Paper presents results of measurements of hydrogenerator´s end region steady state temperatures. Measurements were carried out in case of two hydro-generators, 65 MVA and 40 MVA respectively, installed in the same power plant. Four thermal probes were placed in each of the generators. Some of the tests, carried out for under-excited load conditions, had to be interrupted because the temperature of the end region exceeded 130degC. Results indicate that end region temperature should be monitored.
