Post subject:  transformer for instrument power

In Code IEEE1584, page 6, last paragraph, it requires transformers supplying instrument power and protectvie-device data must be collected in arc flash study, anyone can elaborate it here? I doubt if we have to include this even the transformer is a very small one.
