Periodic transformer failure

I have a 120v to 24vac transformer for a lawn sprinkler system that has
failed about 3 times since I purchased the house. This time I took the
windings apart and found the break in the 120v winding. I live in a
lightening prone area. Is this failure most likely from power surges or is
there some other possible cause.
Thanks.

It helps to ask a clear question... g
Let's say lightning. Then a surge strip might be a good idea.
Let's say 'bad engineering'. THen a better transformer might be a good
idea.
When off how warm/hot does it get?
(There should be little or no heat from an unloaded transformer)
When on how warm/hot does it get?
(the temperature rise should not exceed the point where you cannot put
your hand on it without saying: "OUCH" damn, that's hot.)
Also check your line voltage adn the specified voltage of the
transformer: do they match, or is the transformer rated for a lower
line voltage (bad).
