- Abstract:
- This article analyzes a large number of asymmetric circuits and a variety of typical asymmetric circuits when using a large amount of gas discharge lights. The mid -line current waveform of these circuits was shot. Analysis of these waveforms can be seen: (1) Even though the three -phase load is completely symmetrical, the mid -line current is still 32.7 % of the full load phase current. (2) In the case of typical asymmetric conditions, the mid -line current is greater than the full load phase. (3) If the circuit structure changes, the mid -line current may be greater than twice the phase current. (4) The mid -line current of a three -phase power supply circuit with a large number of gas discharge lamps is not only greater than the mid -line current of the linear load of the same situation, but also rich in high -level harmonics. It is a new harmonic source. These analysis and experimental data control design and cable manufacturers are valuable.
