Can someone help me solve this problem? We have a line carrying a large DC current (say 100 amperes), and we want a device that we can insert to put in or take out a small amount of power (say 10 watts). Assume any reasonable power supply. Now the load on the wire is highly inductive, so the first priority is to keep the current flowing (or deal with a few megawatts...). This is all DC, so a transformer won't work. How the heck do you do this?
