Automated system of the measurement of electric parameters of luminaires and light sources at chosen operational conditions

Quality of electric power is influenced all supplied devices. Due to changes supply voltage are electric parameters what can influence their other features. Therefore for example luminaires are measured at different supply voltage to find out impact of supply voltage to the luminous flux. This paper concerns system of analysis at change of supply voltage on photometric parameters of luminaires. Designed system is appropriate for measurement of electric parameters of luminaires because for them description their behaviour at various level of supply voltage is complicated.
