In this paper, direct current (DC) fault limiting and interrupting operation of hybrid DC circuit breaker (DCCB) using double quench, which consists DCCB, a series resonance circuit, power electronic switch, surge arrestor, two separated reactor/resistor, superconducting elements, were suggested. The suggested DCCB can perform the after twice or once according to amplitude. To verify effective ...

The contribution describes the new measuring and protection system of the VR-1 training reactor. The measuring and protection system upgrade is an integral part of the reactor I&C upgrade. The new measuring and protection system of the VR-1 reactor consists of the operational power measuring and the independent power protection systems. Both systems measure the reactor power and power rate, ini...

In practice, the issue of mixing and chemical reactions is very important in the economic aspects of chemical reaction engineering. A major priority in industrial reactors is to optimize the yield of desired products. This optimization is a function of reactor geometry, the chemical and physical characteristics of the reacting system, the degree of mixing, and the mode of supplying the reactor ...
