Tests with artificial pollution are used mainly for selection and dimensioning of high voltage insulators to be applied in polluted conditions while tests of naturally polluted insulators are used for evaluating flashover performance after removal of insulators from service to assess degree of surface degradation due to long-term exposure to service conditions.

INMR offers expert technical content for power engineers.
About us
Over its 25 years, INMR has produced hundreds of highly practical articles dealing with design criteria, service experience and maintenance requirements of key line and substation components such as insulators, surge arresters, bushings and cable accessories. There have also been many articles on testing these components and also on the manufacturers who produce them all over the world. In addition, the INMR World Congress events have generated many valuable papers on similar and other useful topics applying to these components. Visitors to inmr.com can now benefit from our internal search engine to generate lists of past articles or Congress papers of special interest and which are all now accessible on-line, without cost. We are constantly expanding the numbers of past articles being uploaded so this resource will only grow with time. Visit www.INMR.com often to take full advantage of one of the most valuable on-line information resources for power system design engineers, operating personnel and maintenance specialists.

The TSO in Norway reinforced the transmission grid due to a new HVDC submarine cable connection to Germany and biggest challenge was construction of the 525 HVDC NordLink Line - part of the interconnection and consisting of a 53 km bipolar triplex bundle line that connects to the 500 km submarine cable. #inmr #highvoltage #inmrworldcongress #energy #powersystems #electricalengineering https://lnkd.in/gaCWHvhW

Sheath voltage limiters are sized so that conduction current is negligible during normal or emergency operation. But during transients that induce high sheath voltages, SVLs conduct current to limit the voltage. #inmr #highvoltage #inmrworldcongress #energy #powersystems #electricalengineering https://lnkd.in/gkpBVe6p

Numerical simulations are commonly required for composite insulators equipped with grading rings to ascertain electric fields in sensitive areas, including on the grading ring and end fittings; on the housing surface; and at the triple point where air and housing meet the metallic end fitting. #inmr #highvoltage #inmrworldcongress #energy #powersystems #electricalengineering https://lnkd.in/ge-epFMc
