6.4 Availability of the system's architecture
The system's architecture is capable of connecting different
types of testing equipment and different producers.
The system includes special data models that perfectly suit the
real types of protection devices of different producers. Those
data models are already prepared to use them immediately
after installation. All protection parameters are functionally
defined as soon they are automatically imported from device's
setting files.
In case that the user wants to make his own data model or
repair an existing one, he can do it with absolutely no knowledge
of computer languages. The only recommendation is to
take a couple of training days for system's power users.
6.5 Cost of data handing
Cost of data handling for mobile applications depends on the
organization of maintenance execution. In the case of Elektro
Ljubljana, the implementation of the system has been about
one year. The reason for the delay was related to the strategic
decision by the utility to learn about the system. They generated
their own protection device models, test procedures,
commissioning and maintenance processes. Beside this, there
was quite some volume of data that needed to be collected at
substations and switchgears and loaded directly into the mo-
