   There isn't a single transformer in existance today that will pull 
infinate current, even in short circuit. The transformer will process 
current (Ampers) until the core saturates. My 10 Kva pig will saturate when 
the primary current reaches 110 amps or about 26.4 Kva. That all you get you 
don't get no more.........
