Oil Interceptor Tx, ETx, NER, NCTx
(OP)
Hi,
Do you guys have picture for oil interceptor for Tx, ETx, NER, NCTx ?
Because I'm curious how does RC sump actually help prevent for oil leaking ?
Mayb perhaps inside the RC sumpm, there is a drain which leads the leaking oil to the oil interceptor.

Large transformers are usually provided with a bund which is large enough to contain the entire liquid volume plus 10% or so. This bund will theoretically be able to deal with a catastrophic failure of the tank resulting in rapid oil loss. Many bunds on industrial sites are connected into an oily water drain (OWD) system. It is unlikely that the OWD pipework could cope with a gross failure of a large transformer tank, so the bund acts as a buffer tank. Most OWD systems have a sump somewhere which also acts a buffer tank for the separator which is normally employed to remove the bulk oil prior to treatment.
