This will help us find bad transformers immediately, instead of having to revisit the same transformer several times before we finally take it down.
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.
Great product, and it’s an easy business case – the IFD is a capital expenditure vs. an O&M expense.
