Interpretation Request #1
Topic: Lightening
Clause: Annex B, Table B.2 and Table B.3

Can you please clarify where the quantities of “Number of Flashovers/100km/yr” for corresponding values of “spans between arresters” can be determined from the information stated in Table B.2?

Interpretation Response #1
The quantities are obtained by using the information contained in Section B.4.2 Induced-voltage flashovers. This is the information just previous to Table B.
