Hello all,
I reverse engineered a dog shocking collar and made a fence shocking device,
I used the transformer used in shock collar used for dogs,
Now i need to order similar transformers from a supplier,
But there are many types of transformers that made me confused!
I need help picking something that works for my case,
Any suggestions?
How would we know what your case is? What type of transformer are you looking for. Remember, a transformer is for AC only. If your project requires DC, then a power supply is required that converts the AC to a DC voltage and current you need.
Transformers are usually custom designed and manufactured for large volume commercial applications.
You will probably have a tough time finding a "standard offering" that is similar to what you have, and doing so requires you to characterize what you have rather carefully.
There are plenty of electric fence chargers for sale. Or, build a DIY example using an ignition coil.
I did the obligatory Inet search and found one person that actually measured the voltage as approximately 400V - 500V in this context:
also observed the signal on the base pin of the transistor that switches the battery voltage on the transformer's primary, just to see what it looked like. It turns out that the manufacturer of the collar chose 50μs pulses, 300μs apart by bursts of 50, bursts that are spaced 100 ms apart and repeated 30 times (for a total of approximately 3.5 seconds).

You can do the math to derive at the turn ratio and wind/purchase appropriate. As a do-it-yourself project, winding your own coil is fairly straightforward:
