Industry transformer condition monitoring techniques are widely used by the power utilities for condition assessment of oil-paper insulation systems on industry transformers. Among existings monitoring methods, dissolved gas analysis (DGA) is one of the most commonly used techniques in power industry. Various diagnostic models have been developed based on DGA to identify the fault types of industry...
Large-scale molecular dynamics simulations are performed to characterize the effects of pre-existing surface defects on the vibrational properties of Ag nanowires. It is found that the first order natural frequency of the nanowire appears insensitive to different surface defects, indicating a defect insensitivity property of the nanowire's Young's modulus. In the meanwhile, an increase of the quality...
