There is no doubt the device would be good for the safety of employees to prevent closing a transformer on a fault.
Some of our linemen close in on bayonet fuses on a pad-mount when trying to re-energize it, even though there is no fault close rating. We had a close call recently where a lineman almost got hurt doing that. The IFD would prevent this.
I had a case where I closed in on a faulted transformer, and it spilled oil all over an expensive car located below it. This was an expensive public relations problem for our utility.
