Vintage towers: working it hot - careful planning and full-scale tests enable live-line insulator changeouts at PSE&G

摘要

Competitive pressures combined with regulatory constraints limited new line construction at Public Service Electric and Gas (PSE&G), while demand growth resulted in increased loading on an aging electric transmission infrastructure. Live-line techniques enabled PSE&G, Newark, New Jersey, U.S., to perform routine maintenance functions without taking customers out of service. Live-line work also provided alternatives as PSE&G worked to meet contractual obligations without incurring penalties.
