Doble has put together a proposal on a collaborative study on corrosive sulfur due to some transformer and reactor failures around the world that have been associated with copper sulfide formation. For background information please refer to the information provided.

At this point in time, Doble is seeking companies who are interested in participating in this collaborative study.

For further details on the Study, download the Doble Collaborative Study Proposal
