  12. Voltage Regulator - Advantage Settings • Voltage Set with Line Drop Compensation Paulo Pereira – Brazil – Session 2 – 0993

  13. Methodology Proposed Paulo Pereira – Brazil – Session 2 – 0993

  14. Voltage Control of Each Feeder Flowchart Paulo Pereira – Brazil – Session 2 – 0993

  15. TAP Zones • Define the ideal TAP for each DT with the objective of supply an adequate secondary voltage using primary voltage of the feeder. Paulo Pereira – Brazil – Session 2 – 0993

  16. TAP Zones • The ideal TAP is defined based on optimized voltage range. Paulo Pereira – Brazil – Session 2 – 0993

  17. Voltage Control and Distribution Automation • Data aquisition from customer’s meters and special devices for monitor voltage and load levels. • When necessary change Voltage Regulators Settings. Paulo Pereira – Brazil – Session 2 – 0993
