I wonder if that's also the case in the USA/Mexico border. Can anyone living in San Ysidro or such border towns give us a voltage reading at their normal wall sockets?

Sven, 3Ø voltage on USA side is 120/208
......3Ø voltage in Tijuana is also 120/208.

Thanks Arend for that info, I'm originally from Groningen and lived in Haren, Assen en Loon.
All power there was 220 / 380 Volts.

In the military in Leeuwarden we had 380 /660 for the rotary converters for the 115 / 416 Volts 400 Hz. ( 25 years ago ).

As you say the older parts of Amsterdam,Delft may still have it, and I'm aware of parts of oud Leiden still has 2 phase 127 / 220 Volts. The 127 level is not used anymore and most is now 220 Volts because lamps are not made for that voltage anymore in The Netherlands. The Philips and Grundig equipment had these taps provided for on the transformer primary.

It's probably a matter of the insulation level of the older cables may not cope with a 230 Volts to earth level instead of 127 V. The reason why it still exist even as distribution transformers.


The product of rotation, excitation and flux produces electricty.

I remember doing a troubleshoot on an apartment building at Imperial Beach, CA... (right next door to San Ysidro) My Amprobe showed 123V/121V phase to ground.. SDG&E is pretty good at keeping their voltages in line [Linked Image]

Most old PHILIPS appliances that are stamped with "Made in Holland" are selectable between: 110, 127, 220 and 240 Volts. Even the appliances sold in the 60's and 70's. So i guess some 127 volts services were still used in europe at that time.


I have an old Philips cassette deck from the early/mid 1970s which has those four settings.

I also have some old French-made Moulinex kitchen appliances from the mid 1970s, and the books for those all mention both 220-240V and 127V versions.

I'd guess that 127V was also still in use at that time in at least some of the former French and Dutch colonies in Africa.
