3395: Optimal Placement of Anti-Cascading Structures in Overhead Line Design

This report presents a systematic methodology for determining not only the containment loads on the surviving structure after a cascade but also the optimum location of an anti-cascade structure that will be able to resist these loads after a cascade event. The methodology is based on balancing the initial cost of a line, including the costs of anti-cascade structures, against the future costs of losses due to cascade failure. This includes the expected costs of replacement of the failed section

3420-2: HV Cable Clamping Corrosion Protection Aging Test

Underground Transmission Cables are widely used by utilities to transit power in large urban centers. The most common types of underground construction cables are High pressure, fluid-filled pipeline (HPFF), High pressure, gas-filled pipeline (HPGF), Self-contained fluid-filled (SCFF), and Solid cable cross-linked polyethylene (XLPE). Corrosion is one of the main threats for pipe-type cable and metallic assets systems when exposed to an aggressive environment due to the potential risk factors pr
