Porcelain insulators have long been integral to electrical power systems, valued for their high dielectric strength, durability and reliability under challenging environmental conditions.

A power outage that shut Heathrow Airport earlier this year, causing travel chaos for more than 270,000 passengers, was caused by a "catastrophic failure" of equipment in a nearby substation, ...

Experts say the fire at the North Hyde Substation, which supplies electricity to Heathrow, started following the failure of a high-voltage electrical insulator known as a bushing, before spreading.

The high electric field stress on the high-voltage (HV) end of polymeric outdoor insulator degrades its insulation properties. An alternate approach is needed to mitigate the electrical stresses on ...

In order to study the effect of glaze erosion on the performance of porcelain post insulator, an inclined plane (IP) test similar to IEC 60587 standard was conducted on a cylindrical insulator sample ...

MERIDIAN, Idaho - One of the stranger sights at Meridian's Northwest Lineman College campus is a photo of a power pole straddled by linemen wearing business suits.
