At a flea markte I bought a book about video that dates 1982. The appendix shows a table of worldwide TV systems, voltages and frequencies. Some entries were that weird I wanted to share them - just for fun.
It is sorted by TV systmes.
NTSC: USA System M channels A2-13, A14-83 120, 230, 240V 60Hz b/w: USA

PAL:
UK I 21-68 240/415V 60 (!) Hz, UK
Hongkong I E21-60 200/220/346V 50 Hz
Ireland (ROI) I A-J, 29-43 220/380V 50Hz, Belgian
Luxembourg C, G E 7, 27 110/220V (???) 50 Hz Belgian
NZ B NZ 1-10 230/240/415V, 50Hz CCIR
Norway: 230V only. No 3ph???
South Africa I I4-13, 21-68 220/230/380V 50 Hz, UK

SECAM:
Cyprus B (H) E 5-11 115/400V 50 Hz CCIR
Luxembourg L(V) 21 380V 50 Hz Belgian
Sowjet Union D, K(V) R1-12, 21-69 127/220/380V 50Hz OIRT

All other Eastern block countries aren't even mentioned. GDR had SECAM, some others supposedly as well, others PAL. There are still some videos around that have a sticker: SECAM (GDR) reception!

Well, you could have 60Hz here if you care to run your own generator or converter-set. But then if you do that, you could have anything, anywhere!

These tables are notoriously unreliable, but this one looks worse than most.

Apparently Luxembourg has 110/220V service available for system-C receivers, but you can only run system-L sets on 3-phase! (Seems more likely that Luxembourg was a mix of 127/220 and 220/380 systems 20 yeas ago.)

I wonder why "Belgian" is tacked on the end of several entries?

The Irish listing is almost correct although I have no idea why you would want to use a 380V 3-phase television!

Correct info:

Guess so, I had a real good laugh.
The last entry (UK, CCIR, Belgian) refers to the method of black-and-white transmission.
127/220/380V (i.e. 127V 3ph w/o neutral, 220/380 3ph) was usually listed seperately, but maybe they mixed it up for Luxembourg.
Every country has the 3ph voltage listed if commonly available.
The header said you could have your video equipment converted to work on any system and this was supposed to give you+ TV technician information to do the conversion. Whatever. poor guys if anyone actually tried that.

What's the Belgian method of broadcasting B/W TV?!

This gives you all the technical details of the various systems

No idea. Just copied it from the book.
They say the differences are negligible in most cases.
BTW I'd really love to see the 380V TV set from Luxembourg!

I've seen the odd tourist take that sort of advice WAY too seriously and arrive in Ireland with big bag of utterly useless adaptors.

DJK's link looks a fairly comprehensive reference, and certainly better than most!

Have a look here for a short article on the closure of the old British 405-line system:

"I wonder why "Belgian" is tacked on the end of several entries? "

Yes, I wonder why !?

Sorry for tacking this thred too, Paul!

I see this are a late answer, but:
Noray has 2 systems running, Old 230 delta IT 3 phase or single phase. Newer 230/400 single/3-phase as the rest of Europe.

dsk

Thanks for contributing!
Actually this thread was more about the sheer absurdity of some of those figues than about the actual systems used in those countries.

I mean seriously, 115/400 V in Cyprus? What kind of system is that supposed to be? I'm fairly sure it's actually 230/400 V.
