FAQ's of 500kVA 3-Phase Oil Cooled Distribution Transformer:


Q: How should the 500kVA 3-phase oil cooled distribution transformer be installed?

A: The transformer can be installed using either pole mounting or plinth mounting, depending on site requirements. Ensure a firm foundation and that connections adhere to IS 1180/2026 standards. Professional installation is recommended for safe integration into power distribution networks.

Q: What are the main benefits of using a Dyn11 winding connection for this transformer?

A: A Dyn11 winding connection helps reduce the risk of third harmonic currents and provides phase shift benefits, enhancing reliability. This configuration is also commonly preferred in distribution systems for its ability to handle unbalanced loads more effectively.

Q: When should the tap changer be adjusted, and what is its function?

A: The off-circuit tap changer should be adjusted when the transformer is de-energized to alter the secondary voltage within the +/- 5% range, in 2.5% steps. This feature helps manage voltage fluctuations on the load side, ensuring consistent output voltage.

Q: Where can this transformer be effectively utilized?

A: This 500kVA transformer is suited for industrial facilities, commercial complexes, and utility distribution networks requiring three-phase power at 11 kV/433 V. It operates reliably at altitudes up to 1000 meters and in ambient temperatures between -10C and +45C.

Q: What protections and safety features are incorporated in this transformer?

A: The transformer is equipped with an IP23-rated enclosure, corrosion-resistant epoxy/polyurethane paint, mineral oil insulation (IS 335), porcelain bushings, and high dielectric strength (70 kV). These features collectively enhance safety and extend operational life.

Q: How does the transformer ensure energy efficiency and reduced losses?

A: Built with CRGO silicon steel cores and precision windings, the transformer minimizes magnetic and resistive losses. Its no load loss is limited to 1200 W, with load loss at 4800 W, ensuring that over 98% of the electrical energy is delivered efficiently.
