Experience with bearings and vibration conditions of large hydroelectric units: Waterwheel construction and governing: A study of irregularity of reaction in francis turbines

R. Treat: The device which was developed by Mr. Wilkins, appeals to me as being applicable to investigations of other similar problems. It appears to be a very simple, and it is hoped, reliable device which may be used for determining among other things, the pressures in the interior of oil circuit breakers at the time of opening the circuit and the stresses which are brought to bear upon bus insulators at times of short circuit.
