Article history: Received 25 May 2015 Received in revised form 20 June 2015 Accepted 6 July 2015 Available online xxxx In this paper, we present a case study on Radio Frequency device,where a complete failure analysisflowhas been applied, built through integration of transversal competences from design, testing, and application teams. Key point is using functional failure as electrical fault ac...
The paper analyzes, in brief, various on-line condition monitoring techniques for rotating electrical machines. The different failure mechanisms of electrical machines and several monitoring techniques are analysed. The advantages, disadvantages and reliability of each technique are underlined. A few of the current state of the art techniques are reviewed by surveying the latest developments in...
Power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. Identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. Frequency Response Analysis (FRA) is a new, well-known and powerful diagnost...
