Earlier this year, a fast-growing smart meter manufacturer in southern India found itself facing an unexpected technical challenge. As their engineers prepared to launch a new-generation smart electricity meter, the team realized that their existing CT cores could no longer meet the rising demands of India's rapidly evolving smart grid.
Frequent load fluctuations, wide temperature swings, and stricter anti-tampering requirements meant that their meters needed a more stable, more accurate, and more DC-immune magnetic core.
After months of evaluating samples from multiple suppliers across Asia, Europe, and the Middle East, the team finally received a test batch of DCT 21×16×10 nanocrystalline cores from BIDRAGON.
What happened next was a turning point.
The test results showed:
Exceptional DC immunity
Low magnetic loss
Consistent permeability across temperature changes
High accuracy under real grid conditions
During an internal technical meeting, one of the engineers concluded:
“This is the first core that performs exactly the way our new meter design requires.”
After confirming performance stability, the Indian manufacturer moved quickly from laboratory evaluation to mass production planning. They placed an order for 500,000 pieces of DCT 21×16×10 nanocrystalline CT cores, a key component for their upcoming smart meter product line.
In our production facility, the manufacturing and QC teams worked together to ensure:
Rigorous dimensional tolerance control
Repeated magnetic performance testing
Specialized DC immunity verification
Strong packaging suitable for long-distance sea transportation
Last week, the full shipment was loaded into containers, beginning its journey to India’s smart meter production line.
For the customer, this order represents a major step toward launching their next-generation smart meter across India.
For BIDRAGON, it is another example of how quality, reliability, and professional communication can create long-term trust—no matter the distance.
As India continues its smart metering transformation, we are proud to contribute with:
High-performance nanocrystalline CT cores
Consistent supply capacity for large-volume orders
Technical support for customized solutions
