Porcelain Long Rod versus Cap & Pin Insulators: Impact on Overhead Line Design

Mr. Juhasz graduated from the University of Technology in Bratislava with a BSc and MSc in Cybernetics and later from Applied Math and Automation College in Phoenix. Prior to joining PPC Insulators, he worked at Schneider Electric where he was Group Engineering Manager. He also served as V.P. Engineering at FaradayGrid and has held positions with Siemens managing complex T&D utility projects. His technology background focuses on automation, advanced control algorithms and power electric systems.

A study was completed with the goal of improving performance of a segment of existing 400 kV OHL using new cap & pin insulator strings and new long rod strings given worsened service conditions than in the original design. Different string lengths, towers dimensions and position and number of towers were analyzed, respecting insulation coordination and all other constraints. This presentation covers findings and shows how efficiency of overhead systems can be increased and optimized based on a new tailored porcelain long rod insulator design and professional design tool.
