A method in a power transmission or distribution system, an operator terminal in such a system as well as to a computer program product from such an operator terminal, wherein the operator terminal presents graphical objects representing electrical power transmission control stations together with graphical objects representing power lines on a display, and changes the degree of abstraction of the presentation based on an operator selection or an own selection. A change from a lower to a higher degree involves moving a group of graphical objects including control stations closer to a condensation center point on a power line that is common for this group, and a change from a higher to a lower condensation degree involves moving the group away from the condensation center point. |
