| Description: | Voltage level at which thermal limits are modelled. |
Transmission Constraint Voltage Threshold sets the voltage level at which line and transformer (branch) thermal limits are enforced. This relies on the node voltages being defined a priori. By default all branch limits are enforced if the Transmission Constraints Enabled switch is on.
