Interpreting Single and Double Arrows on Electricity Network Maps: Differences Explained

Question

I have one small question... What does it mean when there are one or two arrows on the map on the mains? What is the difference?

TWK · Accepted Answer

Well, as I wrote before, I encourage you to read the K1 manual - there are even specific thicknesses of lines for these arrows depending on the map scale.

What map is this?

Maybe a colleague can provide more details, some attachment? Geodetic map, single-line diagram? Arrows are used in many cases. I suspect you mean the markings on the poles, but that's just my guess.

TWK · Answer

I suspect that it is about the basic map (and maps for design purposes) and therefore I suggest reading the K1 manual - it can be found in many places on the Internet. There is a specification of what the arrows on the poles mean and when to place them.

Yes, arrows on the poles. In fact, in this case it was an orthophotomap with an overlay of weapons, but it will probably be the same as on the main one.

You have 2 high voltage poles on the plot shown, to determine what power you need to send photos of the whole poles and insulators. Possibly grid locations.

You can tell by the appearance of the pillars power .

. And how do you know he has such poles as he has not provided any map?

Langi_84 · Answer

Since when do poles have power?
Only the voltage level, the material of the pole, the layout of the conductors and the year of construction of the line are important. No more data needed.
Arrows can simply indicate the direction of the line.
A map scan would explain a lot what a colleague is asking about.

Łukasz-O · Answer

And I have a question how does the colleague know what poles the author has on the plot when he has not mentioned anything about it. A glass ball?

zbich70 · Answer

Depends on what you mean by line direction. Only the numbering of poles. Because, apart from radial networks, it has nothing to do with the direction of energy flow.

Langi_84 · Answer

Generally, the line indicates the direction in which the wires run to the next pole. In this case, we have corner columns, at the bend of the line. The number of arrows indicates the voltage level. One arrow means LV, two arrows MV or HV, in this case (photo of my colleague Łukasz-0) 99% of them are two lattice poles of the HV line. There are few cases of MV lines on lattice poles.
As for the numbering of sites, any map other than the map received from the ER will not contain reliable information, and in most cases there will be no such data. Anyway, the pole number alone will not help much, the line number should also be placed.

TWK · Answer

According to K1, there is an arrow and a dash for SN. According to K1, this is the direction of the wires attached to the pole, not the direction of the energy flow.
