American National Standard for Transformers - 230 kV and Below 833/958 through 8333/10 417 kVA,Single-Phase, and 750/862 through 60 000/80 000/100 000 kVA, Three-Phase without Load Tap Changing; and 3750/4687 through 60 000/80 000/100 000 kVA with Load Tap Changing-Safety Requirements
Summary
Revision Standard - Superseded.
This standard is divided into two parts:
1) Part A: “Basic Standard” ratings, characteristics, construction, and routine tests
2) Part B: “Othere” ratings, construction, and tests
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.
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.
