Electronic symbol. Help identify a standard

[pobat]

Sorry for my English.
I write with the help of a translator from google.
Please help determine what standards of a graphic symbol electric (number of the standard paragraph, the part number)?

In one book in Russia were given 4 image transformer (for drawing in the U.S. and Europe).

Аnd did not specify what kind of where taken.
Simply written: IEC (DIN) and IEEE (ANSI)
After learning standards, I thought:
(a) and (b) - IEC 60617
(c) - IEEE 315

Question: Which standards use (d) picture?
In general, I met this image more than once
Here is an example I only found today
site http://www.abacom-online.de/uk/html/splan.html
program SPLAN 7 demo
screenshot of the program

as we see again used this image

in general it is a matter of principle to figure out how this symbol electric :)
I was told that in 1980 ~ such drawing employed in Germany and now in China.
Admittedly this was associated with the use of ASCII artwork "graphics"
Well, when CAD ​​has evolved and it symbol "crossed over" into a modern look
(ASCII artwork "graphics" --> vector graphics)

Help me find a figure emerged from the character and what the normative document is written?
