This dissertation explores three case studies of pharmacologists which had been the Chair of Pharmacology at the Charles University of Prague in the early to mid-20th century and thereafter. Due to their different personal background and research int

Statistical distributions of switching overvoltages have been used for decades for the determination of insulation levels of extremely high voltage (EHV) systems. Existing statistical distributions obtained in the 1970s are for overhead lines, and st

This paper demonstrates the results from a detailed study of the overvoltage protection of a particular 400/150-kV 400-MVA power transformer. The work presented here is based on a real-life power system substation design and data and initiated by Dan

In this paper two methods of validation of transmission network harmonic models are introduced. The methods were developed as a result of the work presented in W. Wiechowski (2006). The first method allows calculating the transfer harmonic impedance

Recent studies of long extremely high-voltage (EHV) cables show the importance of performing temporary overvoltage analyses. As the switching of EHV cables can trigger temporary overvoltages, it is important to find the dominant frequency component c
