As today's buildings become large and high-rise multi-functional, the amount of electrical equipment is also becoming large. Therefore, the study of electrical equipment in educational facilities is diversified. Increased use of electrical energy by industry-academic linkage. Energy conservation is required by increased use of electrical energy. Precision of electrical equipment. The use of advanced transformers requires high-quality power. In particular, measures are needed to reduce energy losses caused by harmonics, which are a factor that reduces power consumption, and continuous measurement and management of power quality are important. Power quality is harmonics. flicker voltage imbalance It can be cited for the reduction of the instantaneous voltage, which rises the instantaneous voltage, and it sets the standards of each country to reduce it as it has the greatest influence by the harmonics. Korea is also stipulated in the Electricity Business Act or the Korea Electric Power Corporation's electricity supply terms and conditions, and efforts are made to install various management devices to improve the power quality and quantify them as they cannot satisfy all of the power quality, so the curve for quantifying them is shown as CBEMA curve or ITIC curve now. In this paper, the factors affecting electric installations of power quality and the methods to prevent them and the regulations to maintain them were presented. It also described measures and problems to reduce electrical energy losses caused by power factor. In order to understand the impact of power quality on electrical equipment, one of the electrical facilities of the educational facility of S University was adopted, and the results were presented by measuring and analyzing the power quality using the measuring instrument.As a result of investigating the quality of electricity through examples, harmonics generation is increasing due to increased use of electrical devices using various transformers unlike in the past. Therefore, the quality of electricity in the power system cannot be shown on the surface, so we will make efforts to use stable and high-quality electricity by periodically inspecting and measuring electrical facilities.
