The current transformer is flexible in the secondary time. You can also use soft cables to plug a pins. It can be installed with a fixed lead.

In many work links, such as quotation, after-sales, logistics, etc., during the epidemic, we did not completely press the pause button, but all departments worked together and cooperated to promote the promotion and development of business and various tasks.

Choosing a current transformer for smart meter projects without causing accuracy problems requires more than checking rated current or one good sample result. The right CT should match the real operating range, burden condition, linearity target, mounting structure, insulation needs, and supplier batch consistency requirements of the project. When these points are reviewed together, buyers and engineers can reduce calibration trouble, avoid hidden measurement errors, and support more reliable long-term smart meter performance.

Buyers should provide clear application, electrical, dimensional, installation, safety, and project information before requesting a smart meter CT quote. Doing so helps the supplier recommend the right model faster, reduces repeated communication, improves quotation accuracy, and shortens the sampling and decision process. A better CT RFQ leads to a better quotation, and a better quotation usually leads to a smoother smart meter project.

DC immunity matters in smart meter current transformer selection because it helps protect measurement accuracy, system stability, and long-term reliability under real operating conditions. In applications where DC-related magnetic bias may affect CT behavior, choosing a design with better immunity can reduce hidden metering risk and support more consistent performance from calibration to field use. For modern smart meter projects, DC immunity is not just an added feature. It is an important part of choosing a CT that can perform reliably in practical, demanding environments.

The right accuracy class for a metering current transformer depends on what the meter is expected to achieve in actual use. High-precision applications may require tighter control, while standard or cost-sensitive projects often benefit more from a balanced and practical choice. The best selection comes from matching the class to the metering objective, operating range, thermal conditions, and supply consistency rather than simply choosing the highest specification available. When accuracy class is evaluated together with real system needs, metering projects become more reliable, more efficient, and easier to control from design to mass production.

In summary, Oswell’s market position as a global provider of metering parts is a multi-faceted advantage.
