Chování taveniny při tavení kovových a nekovových materiálů elektromagnetickou indukcí ve studeném kelímku

The presented thesis is devoted to designing methods for measuring the properties of materials at temperatures higher than 2000 °C and their verification. These are methods for determining liquidus temperature and density. Confirmation of the proposed methods compares the measured and refere...

Inovativní energetické koncepce kombinované výroby elektřiny a tepla

Central cogeneration power plants have already been operated with original technologies for decades. Back pressure turbines have not currently been sustainable technology. Reasons of their unsustainability are operation impossibility during insufficient heat requirements and insufficient operational flexibilit...

Simple calibration method for improving the comparability of PD measurement results at HVDC conditions

Partial discharge (PD) measurement at DC voltage becomes more and more important due to the increased application of HVDC components in electrical power systems. Numerous studies of PD behaviour on various type of insulation at DC have been currently performed to find out appropria...

Dielectric behaviour of natural and synthetic esters at inhomogeneous field conditions

Natural and synthetic esters will be more and more applied as an alternative fluid to the commonly used mineral oil. The application in electrical apparatus needs, at least, the same withstand ability against electrical breakdown or partial discharge (PD) activities as given by the...
