  • Ask me about industrial electricity 2: electric boogaloo

    Here is a 345KV circuit breaker built in the 1960s, and later modified. The Contacts are in the football looking section at the top. The 2 columns on either side which lead to those round tanks contain Current Transformers which monitor, you guessed it, current. It is a SF6 filled breaker, something Three-Phase touched upon earlier.
