Dynamic Line Ratings provide real-time visibility and access at the operator’s console to the true capacity
for T&D feeders.
Dynamic Line Rating (DLR)
Additional Line Capacity
Static Rating (90 MVA)

Without DLR, this event will be reported as a violation (exceeding the static limit) & The operator would have been
forced to intervene for curtailments/ load shedding
