Very fine - and suitable music too. And useful, as I could make good use of those excellent pictures of the fencing. In an effort to convince the authorities of insufficient fencing at a site where a fatal accident occurred - the serious accident happened at a quit similar station in Esbjerg, Denmark. A child was serious injured while trying to get her ball back. Thank you.
Thanks for your rating! I feel sorry for the injured child - you are right: Proper fencing is essential to prevent serious accidents in high voltage areas like these.
Absolutely! By the way, does anyone know why the bus bars in the 380 kV section are kinda pipes / tubes? Is it because of the construction of the pantograph disconnectors?
Might be in order to minimize sharp edges. Sharp edges focus the electric field and therefore create a potential for flashovers, e.g. between two bus bars.
Found a pic on Wikipedia where standard cables are used as bus bars at 220 kV as well. Of course, solid bars aren't affected by wind-induced 'cable dancing' (especially in combination with winter ice) as are standard cables.
That could be another plausible reason. A friend of mine agrees with your point of reducing edges to minimize corona effects / losses. Both reasons make sense to me. Although 'cable dancing' aka 'conductor galloping' is a critical and dangerous phenomenon, it just looks impressive, doesn't it?
Of course it is impressive. But if it goes wrong, you'll learn the hard way that it is impractical to store large amounts of electricity at home. 0.785 kWh weigh in at over 20 kilos in sealed lead-acid battery. Ouch!
There are two types of bus used in switchyards; strain bus (which is ordinary overhead wire strung between 'dead-end' insulator strings, supported on each end), and rigid bus (which is almost always aluminum pipe). Rigid bus requires far less spacing between phases than strain bus. This is because of the tendancy of strain bus to gallop during winds and especially during faults. Closer phase spacing permits the use of less real estate in the switchyard. Some Pantographs require rigid bus.
the towers are pretty neat

Mein Arbeitsplatz das HAW Hamburg Ost
HHFischbek 1 year ago
Oh, cool! Ich hätte mir das am Tag der Aufnahme ja zu gerne auch mal von innen angeschaut und Du darfst das jeden Tag! :-)

Jeden Tag bin ich da auch nicht mal in Nord Süd oder in den Kleinen Abspannwerke über all in der Stadt!
Noch ne kleine info: In Hamburg haben wir Drei HAW also Nord, Ost und Süd und über 70 VAW und ca. 7000 Netzstationen

Yeah, but why do they use standard cables as bus bars in the 110 kV section and those nox-flexible pipes / tubes at 380 kV?
