Controlled Switching of the T402 Transformer in the Križovany 400kV Substation

The paper deals with simulating the circumstances of switching surge and trigger current at switching-in of the T402 autotransformer recently installed in Križovany, with the tests conducted by means of ATP (Alternative Transient Program) simulation software for simulating transient electromagnetic phenomena. The target has been to determine temporal curves for the most critical surge instances against earth and between the phases and the curves for trigger current with and without surge limiters connected, and to determine by means of simulations the size and statistical frequency of switching surges and based on a controlled switching simulation, to describe the elimination of transient phenomena during the process and in reference to the simulations and to operating manual for the PSD02 Siemens control unit, suggest the required configuration settings for the unit.

types, aerobic and anaerobic, based on energy metabolism. Aerobic or endurance exercise is based on improving the cardiorespiratory system by maintaining the intensity level of activity in a low to moderate range for an extended period of time, using oxygen as a primary energy source [ 16 ]. By contrast with aerobic exercise, anaerobic exercise induces muscle contractions in a limited amount of time, stimulating a greater intensity of activity. The primary energy sources for this metabolism are the high-energy phosphates adenosine triphosphate (ATP) and creatine

activity. 23 , 24 Here we explored whether VAS2870, a pan-NADPH oxidase inhibitor, is able to inhibits staurosporine induced cell death in cultured rat astrocytes. Also, we checked how VAS2870 mechanically operates in preventing cell death, since we determined the effect of VAS2870 on staurosporine-induced ROS production, mitochondrial function and ATP level in cultured rat cortical astrocytes. Materials and methods Materials Bovine serum albumin (BSA), Fetal bovine serum (FBS), L-15 Leibowitz medium, Dulbecco’s modified Eagle medium and Ham’s nutrient mixture

four types of strokes (after the serve, return of the serve, baseline strokes and other strokes); and 2) to find differences in three categories of tennis players (ATP players, boys and girls 14 & under). Material and Methods Sample of matches and participants The Faculty of sport Human Ethics Committee at the University of Ljubljana approved the experimental design and protocol prior to data collection. The sample included 15 matches played at a national tournament, in which 14 & under boys (B14) and girls (G14) participated. For the ATP players, also
