Optoelectronic Measuring Systems for High-Voltage Installations Based on Photovoltaic Converters

Resumo

We consider the main principles of construction of optoelectronic measuring systems in which the electric power supply of measuring modules is realized with the help of optical emission transmitted through a fiber light-guide. We present various versions of manufacturing of simple photovoltaic converters with a conversion efficiency of up to 50% based on the photodiode assemblies and AlGaAs light-emitting diodes. The factors limiting the power supplied by the optical emission are analyzed. The possibilities of realization of measuring modules based on self-excited generators with resistive and capacitive transducers based on multichannel analog-to-digital converters are presented. The methods aimed at decreasing the energy consumption of the measuring modules are analyzed.
