FAQs – 750 KVA Transformer
What is a 750 kVA Transformer?
A 750 kVA Transformer is a three-phase electrical device that converts medium-voltage electricity (such as 11 kV, 22 kV, or 33 kV) to low-voltage electricity (such as 415 V) for industrial, commercial, and large residential applications. It provides stable voltage, efficient power distribution, and protects equipment from voltage fluctuations.
Where is a 750 kVA Transformer typically used?
This transformer is used in factories, manufacturing plants, large commercial complexes, multi-storey residential buildings, hospitals, data centers, and utility distribution substations where high-load, low-voltage power is required.
What are the key features of a 750 kVA Transformer?
Key features include high efficiency with minimal losses, robust copper or aluminium windings, oil-immersed or dry-type cooling, voltage regulation taps, three-phase operation, overload protection, and compliance with standards like IEC 60076 and IS 1180.
How should a 750 kVA Transformer be maintained?
Maintenance includes checking oil levels and quality for oil-cooled transformers, inspecting connections and bushings, monitoring operating temperature, cleaning dust or debris, performing insulation resistance tests, and avoiding overload to ensure long-term performance and reliability.
What load can a 750 kVA Transformer handle, and is overloading safe?
A 750 kVA transformer can safely handle approximately 675 kW at 0.9 power factor. Continuous overloading can cause overheating, increased losses, reduced lifespan, and potential failure. It is recommended to operate within rated capacity for optimal performance and safety.
