[volt-nuts] AC Voltage Measurement Standards

[Bob Albert]

I am no expert but there are some interesting ways of measuring AC.  I assume we are discussing true RMS.

Well, you have to have a frequency range in mind.  The more accurate you want to get, the wider the bandwidth, as only a small amount of VHF noise, for instance, still adds to the RMS.  Do you want to include the DC component?

So thermal is a good solution, although it gets cumbersome, especially for high accuracy.  Temperature measurement, thermal insulation, and all sorts of other complications enter.

Anyway, while I have an engineering degree and many years of experience, this is a specialized field and needs pertinent experience, a good physics background, and much more.  Of which I only have a smattering.

I am eager to follow any discussion on the subject.

I've been thinking about adding an AC Voltage Measurement Standard to my

It would appear that most of these have to do with thermal converters.  Does
anyone have any thoughts about this?



I've been thinking about a Fluke 540B, 8506A, or a collection of A55 Thermal
Converters.  I have accurate DC measurement tools and DC standards.



I would appreciate any thoughts.



Thanks in advance.
