Which of the following is typically not associated with power transformers: Cooling Equipment, Sealing Equipment, SF6, or Changing Voltage?

Explanation:
SF6 is not typically used in ordinary power transformers. Standard transformers rely on oil for insulation and cooling, with cooling equipment like radiators or fans to remove heat and sealing to prevent oil leaks. They achieve voltage transformation through turns ratio, which is a fundamental function of any transformer. While SF6 is used in gas-insulated switchgear and some specialized gas-filled transformers, it isn’t a normal feature of conventional power transformers, making it the option not usually associated.
