Abstract
AMAGNETIC oscillograph, with auxiliary equipment, has been found useful at the Grand Coulee Power Plant, Columbia Basin Project, for obtaining information about operating characteristics of hydroelectric units which cannot be obtained from the ordinary indicating and recording instruments. Quantities recorded include mechanical movement, hydraulic pressure, bearing loads, and turbine vibration and noise.
