FAQs of Industrial Electrical Power Transformer:

Q: How is the transformer cooled during operation?

A: The transformer utilizes an ONAN (Oil Natural Air Natural) cooling system, where oil circulates naturally within the transformer to dissipate heat, and the surrounding air cools the oil. This method ensures effective temperature management, promoting longer service life and operational stability in industrial environments.

Q: What tap changer options are available and when are they used?

A: This transformer can be supplied with either an Off Circuit Tap Changer (OCTC) or an On Load Tap Changer (OLTC), depending on the application requirements. OCTC is adjusted when the transformer is de-energized, suitable for steady load scenarios, while OLTC allows for voltage regulation under load, ideal for fluctuating supply conditions.

Q: What protection devices are integrated for safety?

A: Integrated protection features include a Buchholz relay, Oil Temperature Indicator (OTI), Winding Temperature Indicator (WTI), Pressure Relief Valve (PRV), and a silica gel breather. These devices provide real-time monitoring and safeguard the transformer against faults like excessive temperature, pressure, and moisture, reducing the risk of downtime.

Q: Where is this transformer typically used?

A: This transformer is primarily used in industrial power distribution networks across manufacturing plants, large commercial facilities, and infrastructure projects in India. Its robust design and compliance with stringent standards make it suitable for demanding industrial environments that require reliable and efficient power delivery.

Q: What is the process for routine and type testing of these transformers?

A: Routine testing involves electrical, thermal, and safety checks on every unit as per IS 1180 and IEC 60076 standards. Type testing comprises additional comprehensive tests on selected units to assess overall design performance, mechanical strength, and compliance with regulatory requirements, ensuring dependable operation in the field.

Q: How does the Dyn11 winding connection benefit the installation?

A: The Dyn11 winding configuration offers superior phase shift and improved fault tolerance, which helps manage unbalanced loads and reduces issues from harmonics. This enhances the stability and efficiency of the industrial power network, making it a preferred choice for sensitive electrical systems.

Q: What are the main material and construction features that ensure durability?

A: Crafted from high-grade silicon steel for the core and electrolytic copper for windings, the transformer offers excellent magnetic properties and electrical conductivity. The anti-corrosive epoxy powder coating and robust skid or wheel mounting enhance resistance to environmental stresses, ensuring lasting performance.
