Studies in the field of Power Quality have become increasingly important in recent years. International standards establish the limits of the main disturbances that can compromise the quality of electricity. According to GOST 12109-97, the voltage value at the final consumer should be 220 V. Allowable voltage deviations are within ± 5 %, i.e. within 209 V. The maximum permissible short-term voltage deviations can be ± 10 %, i.e. in the range of 198–242 V. All voltage values outside these tolerances do not correspond to GOST 12109-97 and can be hazardous to appliances and equipment in one form or another. The project is related to the development of a sensors’ network to measure Power Quality (with the ability to connect it both wirelessly and by wiring), for the analysis of a low-voltage grid. A wireless smart sensor which includes a transducer converting the value of the physical quantity to be measured into an electrical signal, a circuit for signal amplifying and conditioning, analogue/digital converter and a microcontroller has been developed. The RDF node for measuring basic parameters of power quality which allows connecting to the central computer which can detect the direction of sag events has been developed.
