Earth fault location search
The earth fault location search for the automatic detection of the earth fault location on the negative loop conductor
can only be done on a Soteria system with isolators. It can also only be done under certain conditions, that is, when all
connections are good and there is no short circuit between the loop plus and minus wires.
The earth fault location search is made up of three steps:
1. Occupied addresses search
2. Loop devices map building
3. Earth fault location search
Occupied address search
In the occupied address search, the
device polls all 254 addresses. The
progress is shown as a percentage on
screen.
A list of occupied addresses is
produced, but if there is an issue such
as an empty loop, legacy device, non-
isolated device or dual address, the
search stops and a warning is shown.
