Study on the Performance of Light Sources under Voltage Sag and the Compensation Method

摘要

All kinds of light sources are sensitive to the power supply, which may be shut down when the grid voltage sag or cut off. It will take more than ten minutes for gas discharge lamps to restart due to their cold start features. In this paper, several typical light sources are selected to do voltage drop tests under different amplitude and phase angle, in which the performance of lamps are carried out. Then a compensation method is presented for HID lamps.
