FAQs – 1000 KVA Transformer
What is a 1000 kVA Distribution Transformer?
A 1000 kVA Distribution Transformer is a three-phase electrical device that steps down medium-voltage electricity (such as 11 kV, 22 kV, or 33 kV) to low-voltage electricity (such as 415 V or 480 V) suitable for heavy commercial, industrial, or large residential applications. It ensures stable voltage, efficient power distribution, and protects connected equipment from voltage fluctuations.
Where is a 1000 kVA Transformer typically used?
This transformer is commonly used in large manufacturing units, industrial parks, shopping complexes, multi-storey residential buildings, hospitals, data centers, and utility distribution substations where high-load, low-voltage supply is required.
What are the key features of a 1000 kVA Distribution Transformer?
Key features include high efficiency with low energy loss, 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 2026.
How should a 1000 kVA Transformer be maintained?
Maintenance includes checking oil levels and quality (for oil-filled types), inspecting connections and bushings, monitoring temperature rise, cleaning dust and debris, performing insulation resistance tests, and avoiding overload to ensure long-term reliability and safe operation.
What load can a 1000 kVA Transformer handle, and is overloading safe?
A 1000 kVA transformer can safely deliver approximately 900 kW at a 0.9 power factor. Continuous overloading beyond rated capacity may cause overheating, increased losses, reduced lifespan, and equipment failure. It is recommended to operate at or below rated capacity for optimal performance.
