Their duties include from regular grid inspections based on the results from the inspections, then follow revisions to the transmission lines on which repair is made and are put in function anything identified as a shortcoming and defect identified during the irregular inspection.
The transmission line crews also intervene during breakdowns and they members are trained to react very shortly and repair the defects that might occur for the reasons of atmospheric influences, overloading of grid or other adverse impacts. Inspections are made twice a year, in spring and autumn. After inspections spring and autumn revisions follow.

The measuring and development service is responsible to check the resistance of grounding of the transmission line towers. This office has a mobile crew measuring the grounding resistance on each tower location, on all transmission lines that MEPSO operates with. After the measuring made it analyzes the measured results and if needed provides for additional performance of grounding to tower locations where the results do not satisfy the prescribed technical standards.
