Product Description

 A smart meter is an electronic meter that records data such as consumption of electric energy, voltage levels, current, and power factor. Smart meter displays the users for their consumption behavior in real time, and electricity suppliers for system monitoring and customer billing.

The key component in smart electricity meter is the current transformer. For more than 17 years we have focused on high -precision current transformers for use in smart electricity meters.

    

    Product Characteristics

    1. It applied for energy meters, single phase smart meter or three phase smart meters.

    2. Adopted high quality amorphous alloy and nanocrystalline core, good linearity and high precision.

    3. The CT case adopted flame retardant PBT materials, with good mechanical and electrical strength.

    4. Encapsulated with epoxy resin with strong insulation ability.

    5. DC immune current transformers (DCT) are used in electricity meters, under the influence quantity with DC              and even harmonics in AC current circuit, the accuracy class up to 0.05 or 0.1. Conform to IEC62053-21 

        and ANSI C12.20.

    6. Rosh compliance, CE certificated.
