Tål veteranloken 18 kV? (Elektrifiering/elektrisk drift)

av Per Ljungberg, Thursday, March 19, 2015, 19:54 (3547 dagar sedan) @ Jan Langstrom

De äldre loken hade en märkspänning på 15 kV. Om de tål 18 kV beror nog mycket i vilken kondition lindningen är. En transformator som är omlindad under senare år har bättre förutsättningar än en som har originallindning från t.ex 1930-talet. Eftersom mig veterligt loken inte har lufttorkare för transformatorn så kan fukt i oljan påskynda nedbrytningen. Om transformatorn har utsatts för hög lindningstemperatur så påverkas också isoleringens livslängd.
Det är så långt min kunskap räcker.
