Guys,
Having had the chance to sit down and have a good look at the offered material, this is a site worthy of being linked through here.
Even the Transformer basics are very easy to understand.
Wish I'd had something like this during my training as a Line Mechanic.

I had never heard of using a gas detector to detect faults on transformer. He must be using it to detect long-term events, such as arcing inside the tap changer of the transformer transformer. I would think a high speed differential relay would be a better choice to protect a transformer from internal fault current events.
I used to run the oil analysis program for about 100 transformers in a pulp and paper mill. One thing we always took action on was a transformer that was wet, ie had a hydrogen present in that 200 ppm range. I saw several units that failed above that range.
Good info, I want to look it over some more when I have time.

GcEE,
You would also have to think of the Hysteresis current of that relay coil upsetting the response time, as in a slight delay.
It's a good call on the Gas Detector.
