This paper deals with heat pipes controlled by a static magnetic field. In our previous work we have investigated possibilities of practical use of this method in several types of heat pipes. The major problem seems to be a suitable working fluid with sufficient magnetic ...

The paper discusses the possibilities of using capacitance and tan  measurements in the range of very low frequencies for investigation of the influence of radiation on the special LOCA cross-linked polyethylene flame retardant cable dielectric. It was found that the measured and ...

Substitution of transformer oil as insulator medium by magnetic fluid in transformers requires observation of electric properties of magnetic fluids at temperatures higher than 20 °C. That´s why important physical quantities were measured at temperature in interval from 20 °C to 80 °C.&...

The paper deals with measurement of railway traction transformer using by Sweep Frequency Response Analysis method (SFRA). It was the first measurement of traction transformer SFRA characteristics. In this paper are given reference measurements as well as measurements after type test of ...
