Substation Inspection and Maintenance Software - SIM


At a time of increased competition between energy markets, utilities are forced to rethink their traditional business strategies. The challenge for the operators is to achieve optimized availability of resources, enhance service to customers and reduce overall operation and maintenance costs. To this end, ASD provides a solution to save labor time and cost while performing the most important substations’ tasks. SIM is a web software that serves as a substation preventive maintenance and audit software which helps early detection of substations’ equipment degradation and other defects which will adversely affect reliability.

Along with the technological leap of smart devices, ASD upgraded SIM to be applicable on Ipads and tabs easily and flexibly. SIM is under continuous upgrade to meet further client needs or upcoming technologies.


SIM is always under continuous upgrade to achieve maximum reliability.

SIM is now applicable on smart devices, Ipads, Tabs ...

The Substation inspection and maintenance software can be linked upon request to a mapping system which in turn can be bought individually. The combination results in a whole power network management system. The mapping software displays the main utility network components on the corresponding country’s map taking notice of GPS coordinates and surrounding conditions. The software reveals on the interactive map any changes detected in the database and permits accessing the database from the map.
