To improve pf in three phase circuits, the capacitor bank is connected...
Explanation:
Capacitance Very Small:
- When a capacitor bank is connected in delta configuration in a three-phase circuit, the effective capacitance seen by each phase is reduced.
- This reduction in capacitance helps in achieving a smaller overall capacitance value for the capacitor bank.
- Lower capacitance values are preferred for power factor correction as they provide the necessary reactive power support without overcompensating the system.
Effectiveness of Power Factor Correction:
- Connecting the capacitor bank in delta configuration improves the effectiveness of power factor correction.
- The delta connection helps in balancing the reactive power flow between the phases, ensuring a more uniform distribution of reactive power in the system.
- This balanced distribution of reactive power leads to a more efficient power factor correction and helps in optimizing the power factor of the system.
In conclusion, connecting the capacitor bank in delta configuration in three-phase circuits helps in achieving a smaller overall capacitance value for the bank and improves the effectiveness of power factor correction by balancing reactive power flow between phases.
