When communities on remote islands are connected to an interconnected power system, the reliability of supply gets a boost while customer energy costs are reduced. For the small island of Petersburg, ...

What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

When we were kids, overhead power cables were a constant fixture in the neighborhood. Not only were they the bane of our kites, but they also had a tendency to fail during storms leaving us in the ...

Testing medium-voltage (MV) cables with the high-potential (“hi-pot”) test is typically part of an MV cable testing program. In Parts 4 and 5, we looked at the DC and AC versions of this test. The ...

Researchers at Chalmers University of Technology (Sweden) have discovered that the insulation plastic used in high-voltage cables can withstand a 26% higher voltage if nanometer-sized carbon balls are ...
