Long inter-tier links
If you have a battery installation that is broken up by long inter-tier or even inter-aisle cables, you will
need to consider if you want to keep these in the measurement data set or omit them.
Shown is a graph of a 200µΩ per container (4V wet cells) battery system whose installer kept a single
inter-aisle conductor in the measurement circuit. The ohmic-value of that inter-aisle link is clearly visible
on the graph and will skew the averages for the entire string. However, Frontier can automatically adjust
for this in setting ohmic value alarms. Altering the installation to remove the inter-tier connector can
remove readings like this from the graphs. However, the ohmic value of the inter-tier connector would
no longer be monitored.
Inter-tier links are separated from Inter-cell links for better scaling.
