Well Mike, phasing applies to all transformers. Let's not forget all the modern transformers that have been shipped with phasing issues. If you're suggesting we should throw away all our old equipment because some reader won't know what they're doing, we'll have to agree to disagree.
Greg asked the question, and I suspect he understands the need for circuit protection and phasing. As far as the 99% that don't read OGR, I'm not targeting my response to them, as you say, they wouldn't read it anyway!
