In order for the gas turbine to run upright by itself, what about a fourth part of the maximum speed of the Machine 1 of the Pail int, the turbine drives the machine, which is now starting to work as an alternator. The output frequency increases with the speed of the turbine to a higher "vert" than the irrecuence on the Sannel rails 7. The luariinclfrecuenz of machine 1 is for example in the range between 1000 and 2500 Hs. The sequence generated by the machine 1 is due to the effect of the ji'rerueiizw ./. ndlers 6 on the through the Consumer network certain Ve'rt, for example 400 H-i.
