Dimenzování superkapacitorů pro rekuperaci brzdné energie na základě simulace

The article deals with sizing of supercapacitors for recuperation of breaking energy of tramway line in Bratislava (Slovakia). Based on theory of traction mechanics, a simulation model is introduced. With reference to the tramway line plan and elevation profile, the most valuable line&#...

Měření voltampérových charakteristik pásek a laků používaných jako ochrana před klouzavými výboji u výstupu vinutí čel synchronních generátorů

The paper deals with measurement of coatings used in end-winding of synchronous generators as a protection against sliding discharges. These discharges are due to nonlinear distribution of the electric field along the stator coil. If this protection was not applied, at the machines ...
