FAQs of Distribution Transformer:

Q: How does the Off Load Tap Changer function in this distribution transformer?

A: The Off Load Tap Changer allows you to manually adjust the transformers output voltage by 5% in discrete steps of 2.5%. This adjustment ensures voltage stability based on changing grid or load requirements, enhancing operational flexibility for industrial power distribution.

Q: What applications is this distribution transformer suitable for?

A: This transformer is ideal for industrial power distribution and power transmission networks, serving as a critical component in managing reliable voltage transformation from 11 kV to 433 V across factories, plants, and industrial estates.

Q: When should the transformers oil be checked or replaced?

A: The transformer holds 480 litres of insulating oil (at 500 kVA), which should be checked every six to twelve months. Routine replacement or top-up is recommended depending on operational load and environmental conditions to ensure continued efficient cooling and insulation.

Q: Where can this transformer be installed?

A: Primarily designed for industrial environments, this transformer can be installed at manufacturing sites, substations, or any location requiring medium to large-scale voltage transformation within the stated capacity range (100 kVA2500 kVA).

Q: What are the benefits of CRGO mitered core and copper windings?

A: The CRGO mitered core minimizes energy loss and ensures high magnetic permeability, while copper windings offer excellent electrical conductivity and thermal stability. Together, they improve efficiency, performance, and the transformers lifespan.

Q: How is safety maintained during transformer operation?

A: Safety is ensured by compliance with IS 1180/IS 2026 standards, robust surface treatments, a low operational noise level (<50 dB), and reliable ONAN cooling. Regular maintenance of connections and oil levels further guarantees operational safety and stability.
