电气和光学研究的重点是真空断路器研究。低压网络中的短路状态由特定的测试电路精确再现。为了提高该类设备的分断能力，对大电流演变过程中和零电流区的现象进行了分析。横向磁场解时接触件表面弧柱的位移速度与空间和时间等离子体诊断相关。由于弧后电流是决定短路中断过程质量的重要因素，因此还进行了特定的测量。为了更好地理解真空中的高电流中断，对实验研究的现象进行了数学建模。
Electrical and optical investigations are focused on a vacuum circuit breaker study. The short-circuit regime in the low-voltage network is exactly reproduced by a specific test circuit. The analysis of the phenomena during the high-current evolution and on the current-zero zone is made for the purpose of increasing the breaking capability of this kind of equipment. The displacement speed of the arc column on the surface of the contact pieces in the case of the transverse magnetic field solution is correlated with the spatial and temporal plasma diagnostic. For post-arc current being an important element defining the quality of the short-circuit interruption process, specific measurements are also performed. For better understanding of the high-current interruption in vacuum, the experimentally studied phenomena are mathematically modeled.
