Isolation transformer use beyond test & measurement ?
bob91343:
Since it's a big iron transformer, it will afford some high frequency isolation as well. It will depend on the details.

You can use it to run AC/DC radios if you are a collector of such things.

I used "sag" to refer to a downward spike. Most isolation transformers won't provide voltage stabilization for a prolonged decreased in input voltage. However, some do provide long-term voltage stabilization and are usually advertized as line conditioners. The Sola MCR series is an example. I repeat that one must read the specs to determine if these are true isolation transformers.

Yeah, ideally, but the one I just recently scored is from local electronic recycler, cheap of course, but no reference nor spec. :P
Shot with Fluke 189 for size comparison.

I'm assuming the HF isolation works both ways right ?

With a isolation transformer you can create a system that allows for one ground fault. When system uptime goes first.
Operating rooms are an example of this. You do not want to troubleshoot a tripping RCD when you're working there. So the OR electrical system is floating with monitoring. When somewhere a problem occurs you are notified, and not put in the dark. You can troubleshoot later.
Also very often generators must operate since replacing is expensive and they aren't stock items. But a insulation failure somewhere in the system took out the original control system. When you add an isolation transformer you can tolerate this one fault.
There are still many use cases.
