FAQs of Power Transformers upto 10 MVA- 33 kV Class as per IS 2026 and IEC 60076:

Q: How are these power transformers designed to withstand short circuits?

A: These transformers are engineered following IS 2026 and IEC 60076, ensuring a robust short circuit withstand capability. The construction and material choices guarantee durability even during electrical faults, maintaining operational safety and system reliability.

Q: What customization options are available for winding connections and impedance?

A: Customers can specify their preferred winding configurationDyn11, Yyn0, or othersas well as impedance values (typically from 4% to 10%), to suit their network characteristics and regulatory requirements. This flexibility supports integration into diverse distribution systems.

Q: When should I consider using an on-load tap changer (OLTC)?

A: An OLTC is recommended when voltage levels need adjustment under load without disconnecting the transformer, providing seamless regulation in real-time. This option is particularly useful for applications with variable demand or fluctuating supply voltages.

Q: Where are these transformers best deployed?

A: These transformers are ideal for industrial sites, utilities, and substations involved in power distribution and transmission up to 33 kV. They support both indoor (IP23) and outdoor (IP54) installations, offering versatility across various climatic and physical environments.

Q: What safety features and accessories are provided?

A: Standard accessories include conservator tanks, breathers, Buchholz relays, oil level gauges, temperature indicators, pressure relief devices, and, where specified, OLTCs. These ensure optimal performance, asset protection, and comprehensive monitoring.

Q: How do these transformers ensure high efficiency and minimal losses?

A: Using high-grade CRGO silicon steel cores and precision-made copper or aluminium windings, these transformers achieve over 98% efficiency. Losses (no-load and load) adhere to IS 2026/IEC 60076 standards, and design optimizations are implemented as per specified ratings.

Q: What are the main benefits of choosing these power transformers?

A: Key benefits include high operational efficiency, reliable insulation and voltage withstand capabilities, compliance with international and Indian standards, broad customization options, advanced safety features, and suitability for diverse usage in both utility and industrial power networks.
