World Standards Day 2013 – October 14

Did you know that there is a world standards day? I didn’t!

I searched a bit and found a nice web page:

The results of the World Standards Day 2013 poster competition encouraged me to discuss a bit time and power!

The first price was won by Frederica Scott Vollrath (Germany):

This is really describing what IEC 61850 does: let the power flow through a lot of interrelated gear wheels.

It is one of the most interesting, albeit most challenging aspects of the future power system development because there must be a guarantee that all aspects and tasks of the functions and information sharing services will mesh together like the teeth of gear wheels!!

Well done poster!!

I visited the other day a museum with several of our grand sons (Dynamikum). We saw the following set of 18 gear wheels:


The top wheel is driven by a motor with 250 rpm and 26.5 Watt:


The motor drives the first wheel (large), the first (small) drives the second (large), and so on.


The questions are:

How long does it take until the 18. (last) wheel turns one (1!!) time? How much energy is consumed by the motor during that time?

It takes 3 Million years!!


The motor would consume

26,5 W x 365 x 24 x 3,000,000 h =
7 x 10**2 GWh or
0.7 TWh

That would cost some 128 Million Euro at 0.2 Euro/kwh

Without IEC standards it would be much more expensive! Or?
