Ceramics materials infringe human life from early years of the humankind. Together with the progress of the science and engineering, various materials and technologies have been used. Suitable materials and technologies have been used in the proper applications. This paper…

Modern power electric drives brought advantages in induction motor control. In the same time appeared problems with high frequency square waveform voltage (pulse stress) produced by the voltage converters. Voltage converters produce repetitive pulses with high level of voltage rise…

High operational reliability of the power transformers is one of the most important features. Fast failure detection is the main aim. The power transformers producer faces the customer’s pressure not only for failure detection and prediction. Recently is also requested…

The paper summarizes results obtained during the structural analyses measurements (Differential Scanning Calorimetry DSC, Thermogravimetry TG, Thermomechanical analysis TMA and Fourier transform infrared spectroscopy FT-IR). The samples of cross-linked polyethylene cable insulation were tested via these analyses. The DSC and…
