A protocol to test the sensitivity of lighting equipment to voltage fluctuations

Abstract

The massive application of new lighting technologies and the phase out of incandescent lamps present an important challenge in terms of flicker. The standardized flicker measurement procedure and the existing compatibility levels were based on the response of the incandescent lamp. In order to test the sensitivity of modern lamps to voltage fluctuations, the working group (MT 1) of IECTC34 has developed an objective immunity test protocol. This work presents the main issues that were critical in the implementation of the immunity test system and the results obtained from a set of lamps selected for a Round Robin Test performed by different entities which also took part on the development of the immunity test protocol.
