6. Current Transformer (CT)

   • Measures current flowing in a circuit.
   • Converts high current to a lower, manageable value.
   • Commonly used in metering and protection of electrical systems.

7. Potential Transformer (PT)

   • Measures voltage in high-voltage systems.
   • Steps down voltage to a lower level for measurement and monitoring.
   • Important for voltage monitoring in substations.

8. Distribution Transformer

   • Used to distribute electricity at the final stage from the transmission system to end-users.
   • Typically step-down transformers designed for low voltage applications.
   • Optimized for efficiency and reliability in residential and commercial areas.

9. Power Transformer

   • Used in transmission networks to transfer electrical energy between high voltages.
   • Typically larger and designed for continuous operation.
   • Essential for the long-distance transmission of electricity.

10. Phase-Shifting Transformer

    • Used to control power flow in transmission systems.
    • Adjusts phase angle to manage load distribution.
    • Helps in balancing power across connected grids.

11. Variable Transformer

    • Allows for adjustable output voltage.
    • Often used for testing and laboratory applications.
    • Can be manually or electronically controlled.

Conclusion

Transformers are critical components in electrical systems, each type serving specific functions, from voltage adjustment to current measurement, ensuring safe and efficient power distribution and usage.
