Choosing the best current transformer for smart meter accuracy and stability requires more than checking a few catalog parameters. The right CT should match the meter’s electrical design, mechanical layout, safety requirements, and production goals. When ratio performance, accuracy behavior, burden compatibility, insulation reliability, thermal stability, and manufacturing consistency are evaluated together, smart meter projects can achieve better long-term performance and lower development risk. A careful selection process leads to more stable meters, smoother production, and stronger confidence in field operation.
