Appendix B says to use both synoptic and downdraft for region III. How do you apply this? Does this mean do 2 calculations for every line and use the worst case for your design? I'd appreciated hearing any thoughts on this.
Downdraft always gives a larger value for SRF (see graph) so do you...
When doing a pole load calculation (ie nett load on pole due to conductor loads) what are common load cases you'd look at? eg no wind @ 60deg, wind/ice @ 0 deg etc?
Thanks.
NESC 252B.3 indicates you should reduce the wind load on a power line due to the angle of the wind to line. sag10 has no place to allow for that wind angle. Is this something to be concerned about? Thanks.
