Transformer Protection schemes

[STONE85]

Hello,
Can anyone point me in the direction of any good material for 33kV/11KV transformer protection schemes and how the various relays discriminate with each other.

Thanks

"various relays" - any decent transformer protection today involves two relay, each of which does exactly what the other one does.
