Testing of overspeed protection
When the supply of gas to the gasturbine is not reduced when the generator is going off the grid the shaft might speed up to more then 3000 rpm.
This might result in great damage.
So the protection must be reliable.
Reason enough to test it sometimes.
Here Wytze, Eddy and Bob are doing the test.
Here you can see which valve and knob has to be operated to let the oil pressure drop.
