Computer simulation of induction crucible furnace with supplementary construction element

In this paper the author deals with computer simulation which follows from the requirement of practice. Electromagnetic field distribution around a crucible induction furnace and changes in the distribution of this field using additional structural element (flat short-circuit thread) are solved&#...

Network configuration impact on during-fault voltage in distribution systems

The changes in the supply network configuration can significantly influence the voltage at individual sites during fault events. The main mitigation method against interruptions is the installation of redundant components (parallel feeders, loop system, multiple sources). But the redundant components&...
