1. Dry - type air - cored series reactor 2. Electric reactors air - core electric reactors inductive coils , electromagnetic coils 3. Air - core cable4. Requirements , terminology , and test code for dry - type air - core series - connected reactors 5. Air - core winding6. Air - core power reactor has been important equipment in power system at the present time7. Standard requirements , terminology and test code for dry - type air - core series connected reactors 8. At last , the expression on the mutual inductance of the coaxial air - cored solenoid coil is given 9. We also make an air - core pulse transformer with five hts double - pancakes for the experiment 10. It is the crucial task of this program that develops computer - aided design system for air - core reactor
