While front-end ac-dc converters have changed significantly in terms of efficiency, density, and regulations, power factor issues continue to encumber the users of these supplies. It affects the ac ...
Research addresses high-voltage interference, AC corrosion risk for cathodically protected pipelines
This practice permits measurement of AC current density and evaluation of corrosion products and pits. Recently different criteria to assess AC corrosion risk have been proposed that are based on the ...
Alternating current (AC) corrosion represents a significant challenge for pipeline integrity, particularly where high-voltage power lines and electrified railways coexist with buried pipelines. The ...
In the last six years or so there has been a flurry of reports of AC corrosion on buried pipelines. Statistics are difficult to acquire, mainly because the link between AC and corrosion has not always ...
