ating-Feld fur den S18K250 kann fur diese Werte entnommen werden: imax = 300 A > i * = 100 A Der S18K250 ist also uberdimensioniert. Fur die nachstkleineren Typenreihen ergibt sich: i max = 160 A > i * = 100 A i max = 90 A < i * = 100 A SIOV-S14K250: SIOV-S10K250: Damit erfullt auch der S14K250 die Auswahlbedingung Gl. 9. Da bei direktem Netzbetrieb zumindest die Typenreihe SIOV-S18 (siehe 2.1.2 ) ausgewahlt werden sollte, bleibt es bei dieser Typenreihe. Damit ist eine zusatzliche Sicherheitsreserve gegeben. Energieabsorption des SIOV-S18K250 Die Energieabsorption des Varistors ist direkt mit dem Stostrom korreliert. Damit ist die Erfullung von Auswahlbedingung W max > W * ebenfalls gegeben. Der Vollstandigkeit des Rechenganges wegen wird dies uberpruft: W * = v * * i * * t *r = 640 V * 100 A * 80 * 10-6 s 5 J W max = v max * i max * t r max = 640 V * 300 A * 80 * 10-6 s 15 J Dauerbelastung des SIOV-S18K250 Uber Netzleitungen herangefuhrte Uberspannungen sind in den seltensten Fallen periodisch.

gular wave 80 s, one hundred times. The derating curves for S18K250 in this case show imax = 300 A > i * = 100 A In other words, S18K250 is overrated. With the next smaller types: i ma x = 160 A > i * = 100 A i ma x = 90 A < i * = 100 A SIOV-S14K250: SIOV-S10K250: So S14K250 also satisfies the selection criterion of equation 9. Since at least type series SIOV-S18 should be chosen for direct line operation (see 2.1.2), we stick to this series. Moreover, there will be an extra safety margin. Energy absorption of SIOV-S18K250 The energy absorption of the varistor is directly correlated with the surge current. So this also satisfies the selection criterion W max > W *. For the sake of completeness, this can be checked: W * = v * * i * * t *r = 640 V * 100 A * 80 * 10-6 s 5 J W max = v max * i max * t r ma x = 640 V * 300 A * 80 * 10-6 s 15 J Average power dissipation of SIOV-S18K250 Transients introduced on power lines are very rarely periodic, which makes calculation of the minimum permissible time
