According to IEC62053-21, The energy meter shall be protected against external magnetic field, to face the potential tampering situation. TOPRO shielded Current transformer T-03 adopted customized metal shield (Material: DT4E) for protect against external magnetic field, the shielded CT can be DC immune or not DC immune.
Product Characteristics
1. It applied for electronic electricity meters, single phase energy meter and three phase energy 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) can be used in electricity meters, Conform to IEC62053-21
and ANSI C12.20.
6. Metal shield adopted to protect the CT against external magnetic field 500mT.
7. Rosh compliance, CE certificated.
