Less say if you had transformer in a station it was a 100kv
to 44kv the breaker between the bus an high side of the
transformer protecting it from a fault would be the high
tension. Once it leaves the low side of the transformer it
goes to a breaker that is between the transformer and the
low side bus this would be your low tension. These breakers
have ct that protect the bank with differiential relays.
