Chapter 2 Basics of Vibration Dynamics Vibrations are mechanical oscillations about an equilibrium position. There are cases when vibrations are desirable‚ such as in certain types of machine tools or production lines. Most of the time‚ however‚ the vibration of mechanical systems is undesirable as it wastes energy‚ reduces efficiency and may be harmful or even dangerous. For example‚ passenger ride comfort in aircraft or automobiles is greatly affected by the vibrations caused by outside

NEURAL NETWORK BASED TRANSFORMER DIFFERENTIAL PROTECTION Abstract: The role of a differential relay for power transformer is to trip during fault condition and blocks the tripping during inrush‚ overexcitation‚ CT saturation conditions of the power transformer. Conventional harmonic restrained relay may mal operate due to the presence of the second and fifth harmonic during internal faults because of non-linear loads and capacitance in the transmission lines. This project presents a technique for
