Abstract
This study exposes the measurements of electrical parameters carried out with a power quality analyzer in a transformer. The first measurement taking into account a capacitor bank that was already installed and then taking it out of operation. It presents the results graphed in "Power Log" and analyzed with respect to the standards CFE-L00045, IEEE 519- 1992 and the Regulatory Manual of Technical Requirements for the Connection of Load Centers. By disconnecting the capacitor bank, with the data records obtained from the measurement, it is possible to consider adding a harmonic filter that is presented as the proposal for improving the quality of electrical power, since it achieves an increase from 0.73 to 0.98 in the power factor without compromising the permissible values of harmonics in the system. The filter is calculated and simulated in "DigSILENT Power Factory" to demonstrate the feasibility of the proposal.
