Re: Long distance supply
Ok, there are three seismic sensors into a very long cave, one of these sensors is at 1 kilometre from the entrance of the cave, other sensor is at 500 meters from the entrance and the last sensor is in the mouth of the cave. The power for these sensors are supplied by a group of solar panel outside the cave, because of this there aren't AC lines. What do you think about converting DC to AC (230 VAC) and then in each sensor convert to DC again?.
Thanks to the two.
