A Multi-Microprocessor Traveling Wave Relay - Theory and Realization

an urban industrial area to display geographical distribution network diagrams on the street map on a color full-graphic CRT. The geographical display system displays the distribution network diagrams overlayed on the street map on a color fullgraphic CRT. The status of sectionalizing switches and sections can be displayed. Moreover, the system is provided with other functions such as enlarging, reducing and scrolling of display picture. Fig. 2 shows an example of the geographical distribution network diagram display.
