In order to ensure that conductors have sufficient clearance to the sides as well, the conductor clearance tool can be used to see the blowout of the conductors under max wind conditions. For example, if I have two lines close to each other as shown in the below image, I might want to see what the minimum distance between them is in the event of a blowout.
In order to determine this measurement, we first click on the conductor clearance tool in the left toolbar as shown. The blowout (labelled 'Max wind' by default in the environments field) is shown by the dotted yellow lines on either side of the conductors. By first clicking the conductor clearance tool and then left-clicking the two blowout lines you want to measure between, you will see a magenta line appear between the points to visualise the clearance being measured.
In the clearance information on the top right, you will be provided information on which two conductors the measurement is between as well as the minimal distance between them and the breakdown of horizontal and vertical distances. Please note that the line will always appear where the distance is minimized between the two spans, rather than necessarily where on the span you click.
