WG B2.40 Calculations of the electrical distances between live parts and obstacles for OHL : Preparatory studies for revision of IEC standard (IEC61865 –IEC60826 –EN50341)

Review of electrical and mechanical loading combinations for maximum ground / obstacle and Right-of-Way impact considerations, and update the method of calculation of electric distances between live parts and obstacles for update of IEC and EN standards.

This WG would deal with the loading (electrical and mechanical) combinations for the various along-span clearance situations – maximum operating temperature, ice/snow loading, maximum wind, radial and horizontal/vertical clearances, land use variations. For completeness, the actual corresponding clearances would be noted to allow for comparison between the various country requirements.
