In my EE.SE search today, I noticed that high-voltage
is a really... bad tag. Not the tag itself, but the fact that it's managed to propagate into so many not-high-voltage questions. I'd say 2 of the 10 most recent questions would qualify. The individual voltage
tag is also odd but I see we'd like to off that one altogether: Tags: Voltage, current, and power (oh my)
I'd, possibly, like to offer some alternatives. We currently have high-voltage
and low-voltage
tags according to the IEC definitions but we don't have extra-low-voltage
to round out the classes. Those three tags would leave us with a split of
- (HV) >1000 V
- (LV) 50-1000 V
- (ELV) <50 V
These are nice but I don't think these lines drawn in the sand by IEC play nicely with the questions on EE.SE. Namely, there's too many questions that hover in that 30-60 V range that shouldn't be lumped in with 750 Vrms questions. I think we would actually benefit from using some more intuitive voltage categories instead. Something like this:
high-voltage
(>1000 V)industrial-voltage
(208, 347, 480, 600 V)mains-voltage
(120 V, 240 V)low-voltage
(0 to 50 V)
For the purpose of the site, I don't think it's necessary to delineate medium voltage, high, extra, ultra high voltage, transmission, or distribution levels. Anyone asking those questions will likely get the attention of the right people by tagging high-voltage
or power-engineering
.
Ultimately, I'd just let to set up a watch on actual industrial and high voltage level questions, occasionally look at some mains levels, and ignore questions tagged as high-voltage when someone is using 24 V with a some micro-controller.
high-voltage
tag is used improperly. There's a handful of proper high voltage questions. There is no ELV tag at present, meaning everything else would just be tagged aslow-voltage
... making it as meaningful asvoltage
, IMO. \$\endgroup\$induction-motor
low-voltage
andinduction-motor
industrial-voltage
are usually handled by two different engineers with experience in two different skillsets. Common theory definitely overlaps but not necessarily the standards or practices. Just food for thought. Tags are definitely cluttered already so I also understand not wanting to add more! \$\endgroup\$high-voltage
is 12V in my TTL world. So I guess YMMV, and depends on context. \$\endgroup\$
