ABSTRACT:
A power in a mechanical energy transfer between one of several stationary machines and a shaft assembly is determined. The shaft assembly traverses the machine along a given axis and it rotates about the axis with an angular velocity. The torsion angle by which the shaft assembly is twisted in the machine is measured, and the power in the energy transfer is determined from the product of the torsion angle with a predetermined calibration coefficient. Measuring devices are positioned at the shaft assembly on both sides of the machine which measure the torsion angle. A computer receives the measurement signals from the measuring devices and determines therefrom the power. The system is particularly important in a monitoring system for a machine set with a plurality of machines along a shaft assembly, such as in turbo sets.
