Different tests performed on transformers?

There's not a lot to go wrong in a transformer. You can test with an ohm meter (resistance meter) to check that the wires aren't broken if you know what the connections are. It will read low around 10 ohms if the wires are OK and will read very high if they aren't. However there is a slight possibility that if it is damaged some of the wires may have shorted out so it will still read OK but will overheat when you put full power on it. So you need to power it up and check the output is what it should be with a voltmeter set on AC for a suitable scale. Be careful not to electrocute yourself.
