--- Quote from: tggzzz on March 10, 2021, 01:24:19 pm ---You would be wise to consider failure modes including (but not limited to)... Any equipment on each end is connected to a different phase. There is a difference in the ground/earth/line voltages at each end, especially if there is a line fault or lightning strike. Somebody puts a shovel through the cable, and shorts conductors. Insulation resistance between conductors when water has crept into the cable. --- End quote --- Absolutely good thinking, hence my recommendation to use commercial optically isolated converters.... |

may be you could also get rid of the cable and use a lora network ? |
