A study on the insulation aging assessment and maintenance for submarine medium voltage power cable systems has been performed The purpose of this work is the economic discrimination and maintenance of bad cables which is likely to cause cable system failure. 1 have found that aging status of submarine cable systems are very poor and in progress. Therefore, we have the replacement of cable terminations and repeat the diagnostic measurement Insulation status were improved with the replacement of cable terminations. I have confirmed, with the electrical md structural analysis of terminations, that the poor aging status of cables are mainly caused not by the cable insulations but by the aging of cable terminations. From the above results, I have also confirmed that the domestic diagnostic system is successful and convenient for the discrimination and maintenance of the damaged cables economically.

If the SW weaknesses, which are the main cause of cyber breaches, are analyzed and removed in the SW development stages, the cyber breaches can be prevented effectively. In case of Domestic, removing SW weaknesses by applying Secure SDLC(SW Development Life Cycle) has become mandatory. In order to analyze and remove the SW weaknesses effectively, reliable SW weakness diagnostic tools are required. Therefore, we propose the functional requirements of diagnostic tool which is suitable for the domestic environment and the evaluation methodology which can assure the reliability of the diagnostic tools. Then, to analyze the effectiveness of the proposed evaluation framework, both demonstration results and process are presented.

The global assessment system for medium voltage power cable systems has been developed The minimum purpose of diagnostic activity is the economic discrimination and maintenance of bad cables which is likely to cause cable system failure. I have adapted the Aging Time Constant Method to construct the power cable assessment system for the diagnostic purpose. From the field application test and breakdown test results, it could be concluded that the diagnostic system was successful art convenient for the discrimination and maintenance of the bad cables, which is likely to fail sooner or later, economically.

As the increasing of capacity and technology of power facilities, rotating machines are getting higher at capacity and voltage scale. Thus the monitoring and diagnosis of generators for fault detection has attracted intensive interest. In this paper, we developed fault diagnosis system for monitoring the fault operations in bad power systems. In order to verify the performance of this fault diagnosis system, we made the small scaled testing system which has the same winding structure of the real synchronous generator. The magnetic flux patterns in air-gap of a small-scale generator under various fault states as well as a normal state are tested by hall sensors and the fault detection system.
