A computer-aided stand for testing the power of modern light sources

Abstract

The article discusses the method of measuring the power of modern light sources such as compact fluorescent lamps and lamps based on LED diodes. Receivers supplied with alternating current (sinusoidially variable) draw apparent power from the network. It consists of active and passive power. Modern light sources draw electricity from the grid with a course significantly different from the network voltage. Therefore, it is impossible to accurately measure power in a traditional way. The method of measurement presented in the article uses computer technology which allows for accurate measurement of the receiver's power at any voltage and current course of the receiver.
