I recently attended an electric utility training course discussing relay protection practices. One topic that came up was a fuse saving scheme where a protective reclosing device would momentarily interrupt power to save a fuse from blowing.
My question is how standard electronic devices would react to a very momentary interruption. The instructor said that if power was interrupted for 18 cycles or less on a 60 Hz system that the digital clocks would not reset and blink. I was unable to find any reference to back up this assertion. Are any of you aware of any design standard that would substantiate this claim?
Our practice has always been to push the outage out to the furthest point with a sustained outage rather than "blink" more people than necessary.
