A New Design of M.V – Vacuum Circuit Breaker – With Auxiliary Units Damping Techniques for Soft Interrupter Applications

The dissertation is made with the intention for develop an optimization methodology to create a static switching interrupter-for medium voltage application. Based on the designing and modification of Petersen Reactor Coils Automatic Tuning & inserting of LTT Thyristors for damping technique -main task.

Because of RTU university does not have M.V Laboratory for making sample(s) or verifying of the processes on switching Interrupter. Moreover, the dissertation is analysis of the existing samples for the real experiments. For an instance, some researching papers from the Institute of Electrophysical Apparatus -St. Petersburg, Los Alamos National Laboratory, Behlike Power Electronics LLC -Hamburg / Germany and others.

The work is written in English and Latvian – 103 pages long. Its parts which are, introduction ,3 chapters with main conclusions and four scientific appendixes ,118 scientific information sources including several of industrial samples for both of international academic universities and global industrial firms.

Introduction, the topically of the work was studying, fabricating and analysis the existing of “Petersen Reactor Coils Automatic Tuning” for damping of arcing currents and chopping currents by inserting of a set of LTT Lighted triggered thyristors.
