Scenario Hydro Power Plant The transformer is located near a river dam with extreme logistical and environmental constraints. The option of changing the oil was discarded immediately because of the enormous difficulties in handling (see. Photo) around the transformer. At the same time the fuller earth techniques would not solve the functional criticalities of the system “oil – transformer”. NameplateRead more

For Sea Marconi 2013 ended with very interesting outlooks; one of these involves the opportunity offered by Mexico, engaged in the project for the destruction of PCBs: Environmentally Sound Management and Destruction of PCBs in Mexico. The project, started in 2009, involves the joint effort by the Ministry of Environment and natural resources (SEMARNAT), the Ministry of Foreign Affairs, UNDP (United NationsRead more
