Title: Assessment of the electrical energy quality indicators of 20/0, 4kV transformer station
Keywords: transformer station, quality of electrical energy, indicators, electrical loads

Abstract: The object of study is a 20/0,4 kV transformer station that supplies electrical energy to household customers. The main purpose of the conducted research is to evaluate the quality of electrical energy and total loads of the transformer station. The paper presents the results from a study of the electrical energy quality indicators. An analysis and comparison of the obtained results with the relevant norms given in the regulatory documents [1, 2, 3] have been made.
