The paper presents a multi-channel analytical measurement system for online vibration diagnostics of turbogenerator technical condition. Several types of acceleration sensors with different parameters (supply voltage, frequency band, sensitivity etc.) were used in vibration measurements. Possible variations of the number of sensors, their locations and parameters are taken into account in the system...
The paper presents results of experimental and theoretical studies on small-size piezoelectric generators, in which energy of machine mechanical vibrations is harvested and converted to electric energy. These piezoelectric generators were proposed, as an alternative to a battery-based solution, for powering of sensor nodes in condition monitoring systems of large rotary machines such as turbogenerators...
The paper presents results of studies on piezoelectric generators, in which energy of mechanical vibrations is harvested and converted to electric energy. These piezoelectric generators were proposed, as an alternative to a battery-based solution, for powering of sensor nodes in condition monitoring systems of large rotary machines such as turbogenerators in power plants. Since a performance of three...
