Instrument Survey of the Electricity Supply System

Instrumental survey of the power supply system is carried out to measure the actual load parameters at individual outgoing feedlines in agreement with the customer, as well as for the purpose of in-process monitoring of electric energy quality indicators, for their compliance with the requirements of GOST 32144–2013 “Electric energy. Electromagnetic compatibility of technical equipment. Power quality limits in the public power supply systems”. The article presents the results of in-process monitoring of electric energy quality indicators as compliant with the requirements of GOST 32144–2013 “Electric energy”; values of odd voltage harmonics not multiple of three; values of odd voltage harmonics divisible by three; values of total voltage harmonics; Conclusions on the results of in-process monitoring of electric energy quality indicators.
