The most important issue in the operation of low voltage networks is the protection against indirect contact. For this purpose safety schemes are inevitable that show the places of the fuses and further network information for the assembly workers of the utility. PD-TEAM Ltd developed a software solution for automatic generation of this kind of schemes directly from the Geographical Information System that we now use in production of huge amount of safety schemes. Because of the huge amount of data and the persons affected in this work we use an effitient, tailor made workflow managementet system.
