New Life Cycle Decision Tools for Asset Managers, Engineers and Maintenance Personnel
Screening a service territory for “at risk” substations and transmission line structures requires knowledge of the environmental factors and how those factors impact the structural integrity. That potential damage is categorized by severity and visualized by colors in the steel, zinc and copper soil corrosivity maps and models. GPS coordinates for Substations or Transmission line circuits may be cross referenced to the soil corrosivity maps to determine the corrosion rate severity for that asset. This empirical data allows a utility to choose between various preventative or corrective maintenance philosophies and optimize their O&M budgets by modeling their asset condition. EPRI soil corrosivity maps have been developed by characterizing soils in the laboratory which are then validated by health assessments in a field survey. This practice provides utilities the confidence that their asset management models are accurate due to a high confidence level and a low margin of error.


Technical Notes:

  1. There are some technical issues accessing the maps with certain browsers such as Microsoft Edge and Google Chrome, IT is reviewing the issue but access with FireFox is functional.
  2. All utilities that wish to have viewing privileges must contact Charles Le (chle@epri.com) to obtain ArcGis Enterprise access on the EPRI servers.
