I have no idea about what frequency it is ,the transformer is just fed via 230v a/c and the winding wire is just a secondary on it !.And still no mention of frequency.
Mike.
Yes , going into (fed) into the Primary winding !Is that the voltage going into the primary of the transformer or supplying the circuit?
Mike.
Don't see any mention of frequency in that post.

There is no schematic - simply a partial drawing of transformer windings. If the transformer iron cored, or ferrite? - is it big and heavy?.Has per schematic
It says what it is for at the top of the schematic !No, none at all, he's also rather vague about what it's for - but I suspect it's actually a PAT tester.
Depending on type, size, and weight PAT testers use either a conventional mains transformer (mine does, and takes some lifting) or a small and light switch-mode transformer. From his post #19 (assuming that's the actual transformer) it suggests it's conventional, as it shows separate mains windings
If he posted a picture of the transformer, all would become clear.
It's rather like pulling teeth - but presumably the core of the transformer (as you only posted a picture of the bobbin) is the conventional iron laminations?, E's and I's or whatever. The reason we're all trying to find out more is to confirm the transformer type - a switch-mode type is completely different, and used in smaller more modern PAT testers. In a switch-mode transformer it's likely to be important that Litz wire is used, in a conventional 50Hz there's not really any reason to use it.The problem with the Transformer is in the Primary winding, have had to take off a secondary winding ( the windind wire we are talking about ) to get at the Primary, all the secondary windings are fine, but since I removed that secondary winding I will have to replace with new wire as well has the Primary when I get it unwound .

I want to repair it, the cost of a transformer for it will be way to high a cost, I just need some copper wire !.It's rather like pulling teeth - but presumably the core of the transformer (as you only posted a picture of the bobbin) is the conventional iron laminations?, E's and I's or whatever.

I'm presuming you can't source a transformer .
