Evaluation of flicker measurement uncertainties by a Monte Carlo method

The measurement of the severity of electric light flicker is achieved using a complex model of the human response embodied in a flickermeter. The complex nature of the model leads to variations in flicker readings with voltage input that can be hard to predict. Uncertainty evaluation is therefore difficult to achieve by conventional methods and a Monte Carlo approach is required. This paper describes the implementation of such an approach to evaluate the uncertainty for flicker measurements based on a model of the measurement process.
