Design of electrical machines with low carbon footprint is an actual topic in the industry. Total cost of ownership is the standardized methodology to consider the lifetime costs of a power transformer already in the pre-concept design stage. There still does not exist a widel...

The topic of the article is new insights into the load of transformers depending on their own losses. Transformers are among the most common, but important elements of the transmission and distribution networks. This is a reliable device with a guaranteed lifetime at the level...

Cogeneration power plants have already been operated in the Czech Republic for several decades. These cogeneration power plants have been mostly operated with original technologies. However, these original technologies have to be continuously innovated during the entire operation time. This paper...

Standard short circuit tests of HV SF6 circuit breakers need high power sources and special synthetic facilities. Tests consist of many standard disciplines. Each of short fault disciplines requires high parameters from high power sources. They also require exact measurement and accurately&#...

This paper is focused on modeling of existing cogeneration power plant with backpressure turbine in Pilsen. The first motivation of the modeling is better understanding of all cycle features and its limitations. The second motivation is further investigation of some innovative implementation...
