Re: [PSES] Electric Current Abroad

Always a good idea. As I mentioned to Scott, the final determination, my case, is usually by way of contract with the client/customer. Nevertheless, these lists are helpful in preparing when no other resource is available during the early stages of product development. -Doug Douglas E Powell

Re: [PSES] Electric Current Abroad

The actual paper version of “Electric Current Abroad” (“ECA”) was around in the early 1990’s when I was working at BSI’s Technical Help to Exporters” (“THE”) service, and, even then, I was pretty sure that it had quite a few errors/”generalisations”!– so I really do wonder if it ever got

Re: [PSES] Electric Current Abroad

John, I've heard this ± 10% argument before (circa 1995) regarding legacy UK voltages. It created some interesting discussions with design engineers trying to operate products within a skewed voltage window. One product we developed had a multi-tap autotransformer, with selectable primary to

Re: [PSES] Electric Current Abroad

This does look useful. The Electric Current Abroad PDF document also provides the number of wires from which you can possibly surmise the phase configuration. This almost appears to be the same data converted to a web page. I'm doing something similar on My Drive and combining ISO 2-letter country

Re: [PSES] [EXTERNAL] Re: [PSES] Electric Current Abroad

Absolutely! Thus, an equipment mfr really does need to ask their local importer/agent in the country concerned to confirm the local 3-/1-phase voltage actually IS in the location(s) where that kit will/might be installed/sold – especially in less-developed/”3rd World” countries. John

Re: [PSES] [EXTERNAL] Re: [PSES] Electric Current Abroad

As John noted, some are a “bit different”. For example, you will occasionally find Scott transformers in Japan. Then there is Brazil where you could find practically anything. Single-phase could be 110 V, 120 V, 127 V, 220 V or 230 V. It can

Re: [PSES] Electric Current Abroad

That worldstandards list is, in reality, inaccurate w.r.t. the 3-phase voltages in the UK, and in countries where UK design practice prevails, where the “real world” 3-phase (STAR/WYE config) was/is around 415V (even though the UK now “conforms” to the long-ago EU agreed level of 380V

Re: [PSES] Electric Current Abroad

Hi Doug, Have you seen the list from worldstandards? It doesn't cover the phase configurations directly but does have a column for number of wires. https://www.worldstandards.eu/electricity/three-phase-electric-power/ On Wed, Oct 28, 2020 at 1:48 PM Douglas Powell wrote: > All, > > In the

[PSES] Electric Current Abroad

All, In the distant past I struggled to learn what were the expected electrical voltage, frequency, and phase configurations (delta, wye, high-leg, etc) for commercial/industrial facilities in various countries. I know about IEC 60038 standard voltages, but standard voltages don't always

[PSES] CENELEC Version of IEC 60335-1:2020

When can we expect EN 60335-1:2020? I can't seem to figure this out. :-) BACKGROUND IEC just published in September IEC 60335-1:2020. CENELEC, meanwhile, is working on A15 to EN 60335-1:2012. CENELEC also seems to be working on FprEN IEC 60335-1:2020, on an ambitious timeline, shown here:
