I would appreciate some advice on how to select an electric fencer output transformer. The original transformer was found to be faulty as discussed in the thread below:
https://forum.allaboutcircuits.com/threads/electric-fencer-output-transformer.154966/#post-1335680
The original transformer is shown disassembled in the attached photo. The primary coil has two layers of 34 turns of 1.1mm wire and the secondary has four layers of approximately 160 turns of 0.2mm wire. The ratio then between the primary and secondary is 640/68 which is 9.411 or approx 1:10.
To be compatible with the control circuit presumably any replacement transformer would have to have a similar primary coil along with a similar turns ratio or is there some other requirement for a pulse transformer used in such an application as this. For example, would a relatively standard 220V to 20V mains transformer be suitable?
Best regards
