1. Some dial tones were simply adapted from 60 Hz AC line current . 2. Calculating line currents by using KCL at each delta node gives: 3. The reduced-voltage starter provides the maximum torque with a minimum of line current . 4. These must be designed in line current available resources and infrastructure. 5. As a result, line currents take discrete values of ii, 0 and ii. 6. In power systems it is often desired to eliminate harmonic content found in line currents . 7. The strength of this field is proportional to the line current and in phase with it. 8. "' Boombox "'is a common term for a portable batteries as well as by line current . 9. The third category, space-vector-based modulation, generates PWM load line currents that equal load line currents, on average. 10. Based on measured line currents and voltages, a control system determines reference current signals for each phase.
