An advanced technique for outdoor insulation pollution mapping in the israel electric company power grid

The paper presents the IECo (Israel Electric Co) long-term environmental study aimed at development of Digital Dust Sedimentation Model which provides an Outdoor Insulation Pollution Mapping for Local Grid. The Concept of the study is based on the Authors' idea on strong correlation between IEC 60721 Dust Sedimentation Index vs. IEC TC 60815 Site Pollution Severity Indices within considered geographic domain. The developed Pollution Maps have been validated vs. long-term ESDD-NSDD field-measurements and continuous monitoring of PM

fraction with correlation factors r=0.830 and r=0.697 respectively. To prove the model reliability the calibration was done for different geographic locations in different time intervals. The first-time developed innovative technology is expected to provide cost benefits with respect to dimensioning and maintenance of outdoor insulators, PV-Plants, and other pollution-sensitive local installations.
