Detailed information on the Italian DOSSENA toroidal current transformer:

Italian DOSSENA toroidal current transformer

Italian DOSSENA toroidal current transformerD series, used in conjunction with DOSSENA earth leakage relay DER3 for testing of the same level orDifferential current. In addition to routine testing of leakage current coils, coil testing can also be performed.
The current transformer must be installed upstream of the line or load that requires protection and monitoring. All conductors of single-phase or three-phaseThe body (phase and neutral point) must pass through the interior of the transformer.

The DOSSENA ring current transformer D series is made of magnetic alloy, so its ferromagnetic core can ensure high efficiencyMagnetic properties enable extremely low current values to be detected.
DOSSENA toroidal current transformers come in two specifications: open-loop and closed-loop, with various diameters available,Suitable for different application environments and solutions.
The DOSSENA ring current transformer D series fully complies with the international electrical standard IEC 60947-2:2006 annex Med.4l， Even exceeding the mandatory requirements of the standard, it can achieve a continuous short circuit of 100KA-0.5 seconds.
