Miniature Mobile Systems for Inspection of Ferromagnetic Structures

Patrick Schoeneich

Power plants require periodical inspections to control their state. To ensure a safe operation, parts that could fail before the next inspection are repaired or replaced, since a forced outage due to a failure can cost up to millions of dollars per day. No ...
