Scope

This standard covers certain electrical@ dimensional@ and mechanical characteristics and takes into consideration certain safety features of 60-Hz@ two-winding@ liquid-immersed transformers rated as follows@ and used for step-down purposes: (1) 833/958 through 8333/10 417 kVA@ single-phase; 750/862 through 10 000/12 500 kVA@ three- phase; high voltage@ 2400 through 138 000 volts; low-voltage@ 480 through 36 230 volts; without load tap changing Note: A subgroup of the above group is also identified as three-phase transformers 750-2500 kVA@ with distribution BIL characteristics. (2) 12 000/16 000/20 000 through 60 000/80 000/100 000 kVA@ three-phase; high voltage@ 23 000 through 230 000 volts; low voltage@ 4800 through 36 230 volts; without load tap changing (3) 3750/4687 through 10 000/12 500 kVA@ three-phase; high voltage@ 6900 through 138 000 volts; low voltage@ 2400 through 36 230 volts; with load tap changing (4) 12 000/16 000/20 000 through 60 000/80 000/100 000 kVA@ three-phase; high voltage@ 23 000 through 230 000 volts; low voltage@ 4800 through 36 230 volts; with load tap changing It is not intended that this standard shall apply to dry-type@ regulating@ pad-mounted@ secondary-network@ furnace@ rectifier@ or mine transformers.?
