Isolation Transformers

[Anonymous No.2414440]

Which setup is the best?
Advantages?
Disadvantages?

A. Isolated side is just hot and neutral, ground and neutral not tied, no connected ground.

B. Isolated side has ground and neutral tied, but not grounded.

C. Isolated side has ground and neutral tied, but is connected to it's own grounding rod, not tied to house's main ground.

D. Isolated side has ground connected to the house's main ground. Neutral is not tied to ground at isolation transformer.

E. Isolated side has ground connected to it's own grounding rod, not tied to neutral, not tied to house's main ground.

What exactly is the logic going through your head writing a post like this? Are you an AI? Why list out facts that don't need to be in a list and are mostly redundant even to the ignorant?

If you know what you are doing you do not need any grounding on the isolated side. To provide protection similar to what the US NEC requires, you'd connect neutral and ground to a suitable earth ground, whether it's an independent one, or the one used by your main service panel (C or F which I have added).

exactly the opposite, once you connect the isolated side ground to "real" ground, you lose isolation, which kind of defeats the purpose of an isolation transformer

>isolated side ground
I meant isolated side neutral of course (or rather one of the power carrying terminals you decide will act as neutral). Isolated side Ground (if present) is or at least should be of course connected to supply ground to protect from device failures and should not be connected to neutral.

If you are using something that is not UH compliant, you have to isolate it from all the other UH compliant components. If you are working with signals, then there is a chance you may need one to protect your equipment from power spikes. You also do it when the power in your system is high enough to possibly cause a current leak and exposed metal can harm the operator by contacting the component.

For home and office I don't see a huge reason to have this. Most consumer electronics have some sort of power conditioning. These types of circuit methods are used often in industry.

dude I ain't reading all that shit.

an isolation transformer is line and neutral come in to one side of the transformer and NOTHING is electrically connected to the other side (the secondary) wirings.

If it makes you feel better the ground can go to ground in the outlet but in most cases you don't connect ANYTHING from one side to the other because it is not isolated if you do that.

Here's a clue, asshole: Every transformer is an isolation transformer unless it's specifically made to not be an isolation transformer.

That's basically true, but the transformer pictured has very low capacitance primary to secondary. It is needed for some measurements such as radiated EMI. It also has guaranteed isolation specifications rather than some random numbers.

[Anonymous No.2414607]

>>2414605
Correction. Make that conducted rather then radiated EMI.

Perhaps you'd like to provide ANY criteria?

that's just an inductor.

Autotransformers are common and provide no isolation.

Transformers are really just 2 inductors and a metal core

>Autotransformers
You mean those one kind of transformer that are specifically made to not isolate do not have isolation? I better re-think my whole stance.
>Transformers are really just 2 inductors and a metal core
V8s are really just two inline fourbangers 90° apart, but they're not quite the same thing, are they.

not this guy but lets not forget zigzag transformers.

[Anonymous No.2418822]

>>2418783
I had to look that up. Interesting. I had no idea. In the past I have made a virtual ground for voltage measurements of a 3 wire 3 phase source using 3 resistors and 3 differential voltage probes. The zigzag would provide a much lower impedance, if that were needed.

Autotransformers aren't specifically made to not isolate.
They're used because they're cheap, and they're an easy way to make a transformer with a continuously variable winding ratio.
Not isolating is just a side effect of how they work.
