| 31. | He founded Four-Phase Systems to commercialize the technology, and sold the company to Motorola in 1981.
|
| 32. | Household wiring does not usually use three-phase supplies and the clash only occurs in three-phase systems.
|
| 33. | Aqueous two-phase systems can also be generated by introducing a high concentration of salt to a polymer solution.
|
| 34. | In North America and countries that use their system, the 120 / 240 V split phase system is used.
|
| 35. | In single phase systems without N, both incoming conductors must be disconnected if the incoming feed is shut off.
|
| 36. | Calculations in unbalanced three-phase systems were simplified by the symmetrical components methods discussed by Charles Legeyt Fortescue in 1918.
|
| 37. | Two-phase systems can also be implemented using three wires ( two " hot " plus a common neutral ).
|
| 38. | His main work was in the field of thermodynamics, in which he studied the equilibrium of multiple-phase systems.
|
| 39. | Still, a boost-phase system may do more to enhance American security than the Pentagon's seriously troubled program.
|
| 40. | Three-phase systems can be connected to give various combinations of voltage, suitable for use by different classes of equipment.
