The paper outlines a technical and economical comparison of two power collection concepts for off-shore wind farms: an innovative distributed concept versus the commonly used centralized power collection. In contrast to centralized power collection on a single and large platform, integrated and compact switchgear and transformer modules enable the distribution of power collection across multipl...

Abstract With the rapid development of power systems, switchgear, which is widely used, plays an increasingly important role. Partial discharge one main causes insulation failure a serious threat to personal and equipment safety. In this paper, partial switchgear detected based on ultrasonic method. According characteristics waves generated by discharge, detection method for wave signal designe...

Over the past few decades, lab-on-a-chip (LOC) technologies have played a great role in revolutionizing the way in vitro medical diagnostics are conducted and transforming bulky and expensive laboratory instruments and labour-intensive tests into easy to use, cost-effective miniaturized systems with faster analysis time, which can be used for near-patient or point-of-care (POC) tests. Fluidic p...

Remanufacturing has emerged as a way to solve production problems, raw material costs increase and environmental pollution caused by discarded equipment occurs. The process can extend product lifetime prevent waste of resources. In particular, it economical efficiency for large such GIS (Gas Insulated Switchgear). crucial points in remanufacturing are determining replaceable parts economic valu...

?‘lie paper presents an artificial neural network(ANN) approach using ARTS(Adaptive Resonance Theory 2) to a diagnostic system for a Gas Insulated Switchgear(G1S). To begin with, we will show the background of abnormality diagnosis of GISs from the view point of predictive maintenance of them. Then, we will discuss the necessity of ART-t,ype ANNs, as an unsupervised learning method, in which ne...
