INTRODUCTION In recent years a variety of papers, seminars and conferences have sought to provide detail and promote discussion on the diverse range of issues that make up the electric warship concept. The same period has also seen a huge amount of progress in enabling technologies that have made integrated electric propulsion the system of choice for many new naval ships. This paper looks to r...

The beginning of the XXI century brought a further significant development in the use of autonomous electrical and electronic equipment. The low consumed power equipment is widely used: laptops, mobile phones, PDA, wireless headphones, implants, razors, toothbrushes etc. The higher power consumption equipment is also starting to work wirelessly, e.g. the intelligent machining complexes, robots,...

Since the equipment transmission parts of combination electric appliance in transformer substation are located in the shell, when an internal fault appears, the traditional charged test method only can preliminarily determine the defective position and types, but cannot directly shows the internal defects of the equipment. The Fuxin Company actively introduced X-ray CR imaging test technology a...

Power transformers are essential components of substation equipment for the efficient and stable operation of electric power systems. There is demand for transformers with lower price and higher reliability. In addition, depending upon the onsite conditions, such as narrow roads, mountainous areas or highly congested urban areas, harmony with the surrounding environment is required throughout s...

In recent years, Secondary Substations (SSs) are being provided with equipment that allows their full management. This is particularly useful not only for monitoring and planning purposes but also for detecting erroneous measurements, which could negatively affect the performance of the SS. On the other hand, load forecasting is extremely important since they help electricity companies to make ...
