FAQs of 16 MVA Oil Cooled Power Transformer:

Q: How does the 16 MVA Oil Cooled Power Transformer maintain efficiency in power distribution?

A: The transformer achieves up to 99% efficiency using high-grade electrical steel (CRGO) cores and electrolytic copper windings that minimize energy losses. Oil-based ONAN/ONAF cooling further optimizes heat dissipation, ensuring consistent performance during prolonged operation.

Q: What protection features are included to enhance transformer safety?

A: Safety is enforced through Buchholz relay, winding and oil temperature indicators (WTI, OTI), pressure relief valves, silica gel breathers, magnetic oil gauge, and explosion vents. These accessories provide early warnings and mitigate risks such as overheating or internal faults.

Q: When should the tap changer be used, and what are its options?

A: The tap changer compensates for voltage fluctuations. Off Circuit tap changers are adjusted only when the transformer is de-energized, while the On Load Tap Changer permits voltage regulation during operation, facilitating continuous supply without interruption.

Q: Where is this type of transformer best installed?

A: It is suitable for power plants, substations, and industrial facilities that require reliable distribution and transmission. Designed for ambient temperatures from -25C to +50C and altitudes up to 1000 meters, the transformer adapts to various geographical and environmental conditions.

Q: What is the process for routine testing and commissioning?

A: Transformers are subjected to routine and type testing compliant with IS 2026 and IEC 60076 standards. Tests include measurement of load loss, insulation resistance, ratio and polarity, and verification of all protective devices, ensuring the transformer is fit for installation and operation.

Q: How do users benefit from the ONAN/ONAF cooling system?

A: ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced) cooling systems allow the transformer to efficiently manage thermal loads by utilizing natural convection or fan-assisted airflow. This extends operational reliability and maximizes service life, especially under heavy or fluctuating load conditions.
