ABB also finally found a customer for their DC grid...
Drivesrock,
I truly appreciate the very helpful reply. Yes, the protection scheme does present some, at least, regulatory concerns. Interestingly, Siemens keeps their entire DC bus inside the enclosure lineup shown in the Blue Drive Plus C architecture for Ostensjo Rederi's OSV vessel. ABB...
I've been involved with a little switchgear manufacturing for marine in the US. I've never heard of the equipment actually tested to the inclination levels at all. The vibration test is usually only needed for non-ABS certified components. Go to the ABS website and you can see all the...
While I posted this in the Marine/Ocean Engineering Forum for general comments, I would most appreciate any comments of specific electrical difficulties with these new hybrid type diesel electric systems being proposed by both Siemens and ABB. See here...
Sorry, the ABB link was scrambled for some reason so I'll try adding it as an attachmenthttp://www05.abb.com/global/scot/scot293.nsf/veritydisplay/9aef0fff204391adc12578ab001a3dd6/$file/abb%20onboard%20dc%20grid_flyer_2011.pdf
