    This research analyzed the failures affecting the operation of the power factor correction bank in the paint plant of CIAUTO LTD. The study was conducted using a quantitative approach, including a technical inspection of the bank, verification of the measurement system, and analysis of the electrical parameters obtained during a measurement campaign with the Fluke 435-II power quality analyzer. The diagnosis determined a nominal installed capacity of 105 kVAr, compared to a recorded capacity of 99.4 kVAr. In addition, inadequate connections in the current transformers were identified, associated with differences between the readings of the DUCATI DUCA-LCD96 panel analyzer and the Fluke 435-II. The electrical analysis showed that the power factor varied according to load conditions, reaching values between 0.97 and 0.98 during production and an average of 0.79 under low demand. Based on these results, it was proposed to restructure the bank to a nominal capacity of 130 kVAr, distributed in six steps of 5, 10, 25, 25, 40, and 25 kVAr. For the low-demand condition, a compensation requirement of 4.89 kVAr was determined, and a 5 kVAr capacitor was selected. Simulation in DIgSILENT PowerFactory allowed evaluation of this step, resulting in an increase in the power factor from 0.73 to 0.98 for the analyzed condition. The proposal incorporates backup steps and reuses existing components, improving the adaptation of the bank to the identified operating conditions.
