Remote monitoring for ABB inverters AND their environment The problem: Five significant VSD breakdowns within 1 year. DART was installed to find out why by monitoring the inverters & their environment. A fault alarm was triggered when H2S levels exceeded the preset safe value programmed in DART of 10 ppm, an email was sent to the on-call engineer automatically from DART. Values peaked at 32 ppm H2S on Jan 21st 2025: proving conclusively that a high level of H2S and the subsequent corrosion were the cause of the failures. ... DART case study - corrosion in a WWTW … DART had identified (and verified) the cause of the plant's numerous breakdowns and information could now be provided on how to improve the situation, aiding efficiency, cutting repair costs and downtime and significantly extending the life of the asset.
