TOPRO DC immune Current transformer (DC immune CT) DCT-01 is used in electricity meters, under the influence quantity with DC and even harmonics in AC current circuit. We adopted high quality amorphous alloy and nanocrystalline core for DC immunity Current transformer, with good linearity and high accuracy up to Class 0.2, Class 0.1
Last year, We developed a type new 60A DC immunity CT with compact size/ small size, the external diameter is 22.5mm only, the DC tolerance is less than 3%,Conform to standard IEC62053-21.
Product Characteristics
1. It applied for IEC meters and ANSI 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
6. Rosh compliance, CE certificated.
