Liquid insulation is one of the ways of ensuring transformers – which convert electric power from high voltages to lower voltages – remain safe. Mineral oil, however, has been the main insulating ...

U.S. electricity consumption continues to increase almost 2% annually. As the load growth spurs calls for new power plants and transmission lines, it’s easy to forget the impact of the additional ...

Accra, Sept. 3, GNA - The Environmental Protection Agency (EPA) has started a programme to eliminate transformers and capacitors that contain a chemical called Polychlorinated Biphenyls (PCBs) which ...

Thermo Fisher Scientific has developed an innovative gas chromatography (GC) method for the determination of polychlorinated biphenyls (PCBs) in mineral insulating oil using solid phase micro ...

EASTHAMPTON -- A recent rainstorm brought down a wooden utility pole with an old electrical transformer, releasing 15 gallons of PCB-laden oil near the Connecticut River oxbow. Eversource reported the ...

Polychlorinated biphenyls (PCBs), a group of 209 chemicals that have very good thermal and electrical insulating properties, were widely used in industrial applications for decades beginning in 1929, ...

PCBs are a health risk because they build up in the environment, accumulating in the tissue of fish and other aquatic animals. In addition to causing cancer, PCBs can affect brain development and ...

The degradation of transformer insulating oils through corrosion represents a critical challenge for the reliable operation of power transformers. Corrosion mechanisms are intricately linked to ...
