The master's thesis deals with the manufacture of high-voltage diode for the purpose of laboratory measurements of high-voltage equipment under the influence of the DC voltage. The emphasis is on own designed and manufactured diodes which have been tested in high-voltage laboratory of Milan Vidmar Electric Power Institute.
The first section describes the basic concepts that have been of the utmost importance for model production. These were primarily specific parameters such as electric field, properties of insulation, electrical materials etc. In the second part of the master thesis I focused more on the physical basis of pn-junction diode which has been a key element of practical work as well as on existing solutions which are used today.
In the end, number of practical tests that were carried out during all the research and manufacture of high-voltage diodes are presented. I came to the conclusion that despite the successful completion of the project the influence of the electric field at voltages higher than 300 kV is such, that the structural design of the rectifier diode by successive assembling is extremely complex and in the manner as described in the thesis is not suitable for serious use.
