Transformer bushing is an outlet device which leads the internal high-voltage to the outside of transformer. It is not only an important part of power transformer, but also is very important power transmission equipment. The effective condition assessment for transformer bushing, to guide the operation and maintenance of bushing and reduce the failure probability, have an important theoretical and...
For the urgent needs of the bushing test technology and inspection method with the rapid development of UHV transmission project, based on the technical requirements of the UHV transformer bushing and use for reference on the existing transformer bushing test technology, a complete set of UHV transformer bushing test system including insulation test, thermal rise test has been established, and also...
Class imbalance of datasets is a common problem in the field of machine learning. In recent years, because the traditional classifier algorithms are designed only for balanced cases, these classifiers always achieved poor performance in imbalanced data classification issues, especially for the imbalanced data with a really high density. This paper introduces the importance of imbalanced data classification...
In this paper, a micro-optical-electro-mechanical system (MOEMS) gyroscope was developed taking a new optical microcavity - planar microdisk cavity as the core sensing element. The planar microdisk cavity was designed with high Q value and small volume, and the processing technology of the planar microdisk cavity was discussed in detail with the micro-nano machining process technology. To obtain resonance...
