Product Introduction
The IVY Metering IVY-CT-05-100ADC-500mT is a DC-immune metering current transformer designed to protect electronic energy meters from external magnetic tampering. It combines an amorphous alloy and nanocrystalline core, metal shielding with 500mT magnetic immunity, a flame-retardant PBT case and epoxy encapsulation. Available as a finished U-shaped copper CT or as a semi-finished customizable CT. Designed to meet IEC62053-21 magnetic immunity requirements for energy meters.

Product Characteristics

• Suitable for electronic single-phase and three-phase energy meters and other metering devices.
• Amorphous alloy and nanocrystalline core for excellent linearity and high metering accuracy.
• CT housing made of flame-retardant PBT providing mechanical and electrical strength.
• Epoxy resin encapsulation for robust insulation and environmental protection.
• DC-immune design compliant with IEC62053-21 for reliable metering in presence of DC or external magnetic fields.
• Metal shield protects the CT against external magnetic fields up to 500mT.
