Improved performance (transmission) gratings [PDF]

open access: yes, 1978
Results of the study produced the following conclusions: higher line density gratings could be produced immediately by superimposing existing gratings (after reducing wire widths); unwanted higher orders could be reduced by chemical treatment of existing ''deep groove'' gratings; symmetric phase gratings could be produced immediately by plating with a ...

Experimental and Numerical Study on Stray Loss in Laminated Magnetic Shielding Under 3-D AC-DC Hybrid Excitations for HVDC Transformers

open access: yesIEEE Access, 2020
To investigate the stray loss in magnetic shielding components immersed in the 3-D AC-DC hybrid leakage magnetic field, a modified method is presented with the variation of the eddy current loss inside the coil due to the change of the leakage magnetic ...

Fault Identification of Broken Rotor Bars in Induction Motors Using an Improved Cyclic Modulation Spectral Analysis

open access: yesEnergies, 2019
Induction motors (IMs) play an essential role in the field of various industrial applications. Long-time service and tough working situations make IMs become prone to a broken rotor bar (BRB) that is one of the major causes of IMs faults.

Electricity Transmission Pricing and Performance-based Regulation [PDF]

open access: yesThe Energy Journal, 2005
Performance-based regulation (PBR) is influenced by the Bayesian and non-Bayesian incentive mechanisms. While Bayesian incentives are impractical for direct implementation, the insights from their properties can be combined with practical non-Bayesian mechanisms for application to transmission pricing. This combination suggests an approach based on the

Optimized configuration and characterization of LCC-S based wireless power transmission system

open access: yesWireless Power Transfer
A mathematical model has been established for the LCC-S magnetic field-coupled wireless power transfer (WPT) system, and its impact on transmission performance has been analyzed from two aspects: working frequency (f); and the ratio of primary-side ...
