ABSTRACT

The paper presents an analysis of the power quality in a trader with special technological equipment that requires continuous power. We found very high levels of capacitance energy injected in the electric network, confirmed also by the electric energy bills. After the recorded tests and measurements, we found the generating sources, namely the three power supplies UPS, each of 250 kVA capacity. To remedy this problem, we proposed a number of measures including the installation of a passive filter (inductive) to compensate the capacitive load.
