FAQs of Electrical Power Transformer:
Q: How is the electrical power transformer installed and where can it be mounted?
A: The transformer is offered in both skid and wheel-mounted configurations, providing flexibility for indoor or outdoor installation. It comes with enclosure protection (IP23/IP44) and can be mounted as per site-specific requirements, ensuring safe and stable placement in power distribution or transmission settings.
Q: What are the main benefits of using a transformer with insulation class A, F, or H?
A: Insulation classes A, F, and H define the transformers maximum operating temperature limits. Higher insulation classes, such as F and H, support hotter operating environments, improving safety, reliability, and lifespan, especially in regions with elevated ambient temperatures or high electrical loads.
Q: When should the on load tap changer (OLTC) option be selected for this transformer?
A: An OLTC should be chosen if voltage regulation under varying load conditions is required, such as in distribution networks with fluctuating demand. The OLTC provides +5% to -15% voltage adjustment in 2.5% steps, ensuring consistent performance and voltage stability as operational needs change.
Q: What materials are used in the construction of the transformer core and windings?
A: The core is fabricated from high-quality Cold Rolled Grain Oriented (CRGO) silicon steel, and the windings utilize high-grade copper. This combination ensures minimal losses, high efficiency, and structural durability throughout the transformers service life.
Q: How does the transformer ensure operational safety and compliance with standards?
A: Each unit undergoes short circuit withstand and dielectric strength tests according to IS/IEC standards. Features like oil-immersed cooling (ONAN), solid bushing choices (porcelain/polymer), and robust enclosure options help maintain compliance and enhance safety for a wide operating temperature range.
Q: What range of capacities and voltages are available for this transformer?
A: Transformers are available with rated high voltages of 11 kV, 22 kV, or 33 kV and low voltages ranging from 415 V to 690 V. Their capacity reaches up to 2500 kVA, with dimensions and outputs fully customizable to specific project needs.
