Re: [TCML] instrument Transformers VIL95S

Hi,

Nice potential transformer. Your transformer is conservatively rated by 
ABB for 1000 VA at 30C for continuous 24/7 operation. For intermittent 
duty (i.e., Tesla Coil usage), you should be able to easily push it to 
2000 VA with no problem. This translates to 2000/12000 or around 170 mA 
RMS. For short run times and much longer cool down times, you can push 
it another 50% (to 3000 VA or 250 mA RMS).
Be careful to appropriately current limit it via an external ballast. 
And, treat it with utmost respect, since its every bit as dangerous as a 
distribution transformer.
