Experimental steam turbine with five high pressure stages results is described. The great effort is paid to the steam parameters over the individual stages during gradual start-up to nominal operating parameters. Especially pressures and temperatures as well as isentropic and used enthalpy drops are presented during idling, heating up and during transition to operation speed of the turbine. Specifically problems with enthalpy drops and thus efficiency measurement are described in detail.
