AIS preliminary survey is a simple tool for evaluating the need for a more in-depth assessment carried out by ABB. Its use is strongly recommended for those plants where conventional maintenance strategies are still applied and no other assessment has been performed.
Check each environmental and operational condition, compare the plant situation with given range/status values and select one check button for each field group. Fill in the number of years since the last ABB assessment was performed and click on the Run check button to get the survey result.
Environmental conditions (Id numbers from 1 to 4) refer to the entire switchgear including the period in stock at site, whereas the operational conditions (Id from 5 to 10) relate to the most critical installed device.
