IMPROVING WEIGHTING FILTER OF UIE/IEC FLICKERMETER - BUILDING THE LAMP MODEL

The weighting filter is the key part to improve the accuracy of UIE/IEC flickermeter. The lamp response, which depends on specific lamp type, is an important part of the weighting filter. To improve the weighting filter, the lamp response model of different types of lamps should be used. A useful and simple mathematical lamp model built by system identification methods is presented in this paper. This model is derived from the measurement data without consideration of physical characteristics inside lamps. This model can be used for different lamp types with different parameter set. Thus, the measurement accuracy of the weighting filter and the flickermeter could be improved.
