Ken et al,
Remember that the standard EE definitions are: Low Voltage
(up to 600Vac), Medium Voltage (e.g. neighborhood distribution - 10s of kVs)
and High Voltage (transmission voltages maybe 100 kV and up).
What we work with in electronics is, for the most part ELV
(Extra Low Voltage) which has multiple definitions but all selected to be
'safe' in some way; the most common definition is 30Vac/42.4Vpeak (with
higher limits for DC). Further sub definitions also exist; IEC 60950
promulgated SELV (Safety ELV) with specific requirements and has been used
by the computer and electronics folks for 40 years.
So, were the folks promoting this usage really considering
High transmission voltages?

Not at all helpful, but I have always wondered why, if we speak of high
voltage, we don't also speak of high amperage and high ohmage?

Subject: [PSES] High voltage versus High tension
Hi folks,
I never encountered this before but am curious if anyone had any problems in
using the European verbiage 'High Tension' in lieu of 'High voltage' during
their 61010 assessment on their labels and documentation.
Unless I am mistaken on the Group & National differences, IEC 61010-1 does
not mention anything specific on allowing this alternative language.
I also want to know if 'High tension' would be a problem in the USA and
Canada during a Field evaluation or NRTL certification? (I only ask to avoid
having 2 labels/wording on a global product)
Thanks for sharing any experiences you had.
Regan Arndt
