For that reason, asset management has become an increasingly important aspect of corporate business strategies. A significant focus of EPRI’s asset management research in recent years has been to develop a rational basis for selecting repair or replacement options for specific classes of equipment by balancing the risks of equipment failure against the costs of continued maintenance or ","cbCaitRTsUbyVpnx","https://ap.wps.com/l/cbCaitRTsUbyVpnx","pdf",347813,90,"English","# Results & Findings\n## Product Description\n## Challenges & Objectives\n## Applications","[{\"question\":\"What is the main purpose of the report?\",\"answer\":\"The report provides data on equipment failure mechanisms and preventive maintenance to systematically estimate failure rates for distribution-voltage-class protection components.\"},{\"question\":\"Why are failure-rate estimates important for utilities?\",\"answer\":\"Failure-rate estimates help utilities decide when to replace assets and support asset management investments by enabling multi-year life-cycle business cases.\"},{\"question\":\"How does the report propose estimating equipment failure rates when maintenance records are insufficient?\",\"answer\":\"It develops an alternative failure model that combines expert judgment with available data to generate interim failure information for asset management.\"}]","Equipment Failure Model and Data for Distribution-Voltage-Class Protection Equipment - A PM Basis Application - Technical Update | PDF",1789148613,31,{"code":4,"msg":81,"data":99},[100,104,109,114,119,124,129,134,139],{"id":101,"doc_module":22,"doc_module_name":25,"category_name":102,"show_sort_weight":91,"slug":103},11,"Presentations","presentations",{"id":105,"doc_module":22,"doc_module_name":25,"category_name":106,"show_sort_weight":107,"slug":108},12,"Resumes",80,"resumes",{"id":110,"doc_module":22,"doc_module_name":25,"category_name":111,"show_sort_weight":112,"slug":113},14,"Invoices",70,"invoices",{"id":115,"doc_module":22,"doc_module_name":25,"category_name":116,"show_sort_weight":117,"slug":118},15,"Posters",60,"posters",{"id":120,"doc_module":22,"doc_module_name":25,"category_name":121,"show_sort_weight":122,"slug":123},16,"Social Media",50,"social-media",{"id":125,"doc_module":22,"doc_module_name":25,"category_name":126,"show_sort_weight":127,"slug":128},17,"Forms",40,"forms",{"id":130,"doc_module":22,"doc_module_name":25,"category_name":131,"show_sort_weight":132,"slug":133},18,"Letters",30,"letters",{"id":135,"doc_module":22,"doc_module_name":25,"category_name":136,"show_sort_weight":137,"slug":138},21,"Paper Templates",5,"papers-templates",{"id":85,"doc_module":22,"doc_module_name":25,"category_name":29,"show_sort_weight":4,"slug":140},"general-158"]
