Title
(EN) SEQUENTIAL, CLAMPED, SINGLE-ENDED IGNITION OF SERIES OPERATION ARC LAMPS
(FR) ALLUMAGE SEQUENTIEL SERTI PAR UNE SEULE EXTREMITE DE L'AMPE A ARC MONTEES EN SERIE
Abstract
(EN)
A series of arc lamps (6-8) is ignited sequentially while maintaining a specified voltage on one side of each lamp (6-8) with dielectric insulation on the high voltage side.
(FR)
L'allumage d'une série de lampes à arc (6-8) se fait séquentiellement tout en entretenant une tension spécifiée d'un côté de chaque lampe (6-8), le côté haute tension étant pourvu d'une isolation par diélectrique.
