[2023] Function of Explosion Vent in Transformer

  The main function of the explosion vent in transformer is to expel the hot boiling oil and over-pressurized gas from transformer to atmosphere in-order to avoid explosion due to excessive pressure build up in the main tank during heavy internal faults. It acts as an emergency exit for hot boiling oil and hot air gases present inside the main tank during heavy internal faults.

  The raise in temperature of transformer oil can cause major ( or huge) problem in the transformer, if it is not treated properly. When heavy internal fault occurs in the main tank of the transformer, winding generates heat due to which pressure increases.

  It prevent explosion and other damage to the main tank from excessive pressure due to heavy internal faults. It works as same as the safety valve works in the pressure cooker. Hence, in other words we can also call “the explosion vent is the safety valve in case of the transformer” and used to control damage in transformer and a part of power system.
