Start-up phase of the high pressure mercury lamp feeded by an alternative current. Application to the study of a dynamic regime for lighting micro-network

摘要

Summary form only given. The lamps electrical characteristics evolution during their warm-up phases generates variable harmonic currents circulation. These harmonic currents induce, in some cases, constraints that cause ominous effects on the supply network (regime of the neutral, unnecessary losses in ballasts and the transformer of feeding, etc.). To understand and analyze the electrical phenomenon evolution in a lighting network, it is desirable to simulate the lamps-circuit system. So, in this work, we have studied the interaction lamp-circuit supplied by alternative current with a variable pressure LTE model that describes the most important phase of the dynamic regime. This phase covers the most interesting electrical phenomenon (variation of the arc voltage of 40 to 150 V).
