I've ran into this issue a few times at my plant. We have a blown fuse, but we will still get continuity AND voltage. I know you can read through a coil or xfmr so I get why sometimes you will have continuity, but the voltage is throwing me off. We have two fuses protecting a 480 to 120V (250VA) control transformer. I have 280 to each of the two fuses, on both the line and load side. I even have 280 at the xfmr, but when I go leg to leg I have 0V. Because I've ran into this before, I pulled the fuses and re-checked them, and sure enough, they were no good. How can this happen?
