But the proplem is that I have not any formulas :) that's why I've asked here

No, no. As collision I mean that in the distance from conductor there is a part of an object. So for an example in distance 5,50m from conductor i have a tree.

@PhanthomJay thank you for Reply! I have a lot different power lines, sags, materials, and other parameters. That is the biggest problem, that I need to prepare tool to calculate maximum current for given parameters. Now I have working tool that do what you posted. I change temperature until I...

If you have right so then how to calculate conductor temperature from environment temperature? I'm almost 100% sure that we use temperature of conductor to simulate sag etc.

This whole article isn't a very good example of my calculations or the whole process of detecting collisions. I just tried to use some similar formulas. In our soft in the collisions detecting, we have included sway of power lines and icing. But still, I think that this mathematical formula is...

@anorlunda Not exactly. I'm working in GIS company, that analyze power lines for clients, including potential collisions with dangerous objects and remarks like a damaged pole. One of the clients wants to know what the maximum current in "safe exercise" can have on each power line that they...

OK, probably I need to start again in other way. I'm analysing HV power lines and theirs potentially collisions with vegetation. To calculate these collisions I use temperature, wind, material, and other parameters that affects the line sag and the swing. It works good from years, so we can go...

Thank you PhanthomJay! So if I have the maximum temperature that a conductor can handle how can i calculate the macimum carrent for this parameters that shouldn't be dangerous? EDIT: I think, that I need a max current in given temperature. Can someone help me with mathematical formulas of this...

Hello All! I'm new in this forum, so if I select wrong subject or something then sorry. I'm very, very far from physic, so I need your help. In work, I have to calculate max current for HV power line. As input have conductor temperature [*C] and material parameters (the resistance in ohm of the...
