Substations equipped with oil transformers and oil circuit breakers must be fitted with emergency exhaust fans； Do dry-type transformers and high/low voltage substations still need to be equipped with accident exhaust fans? Which standard clause specifies this?

The new standard \"DLT 5725-2015 Code for Construction of Substations for Power Users at 35 kV and Below\" has been found. According to 15.4.1.2, the distribution equipment shall be equipped with emergency exhaust fans that can provide at least 10 air changes per hour; such fans can also be used for normal ventilation purposes.
