Thank you for the response, the transformer is hermetically sealed transformers., it doesn't have the conservator tank and breather systems. Hole at corrugated fins oil came out from those fins at the time of failure.
we observed there is no high temperature in oil at time of incident.

Oil temperature not that much max reach was only 50 degrees. Because the transformer is indoor unit and there is three split ac unit in the room.
Recently, this transformer is failed , due to the internal short circuit..I suspecting that this kind of frequent cyclic operation lead cause for the...
We have a 1000 kVA distribution transformer subjected to frequent load cycling — around 12 to 15 ON/OFF cycles per day. Each cycle consists of the load being ON for 30 minutes (reaching approximately 70% of the transformer’s rated capacity) and then OFF for 30 minutes. The connected loads are...
