PRODUCT DESCRIPTION

A transformer’s magnetic core may become magnetized as a result of DC current testing (such as winding resistance measurement), or when the transformer is taken out of service. In order to avoid problems such as the incorrect operation of protective relays, high inrush currents, or erroneous diagnostics, it is recommended to perform demagnetization to eliminate this source of potential problems.

Upon completion of the demagnetization process, instruments provide information about the initial and remanent magnetism, proving that the transformer is successfully demagnetized.

DV Power automated three-phase transformer demagnetizers enable safe, fast, and efficient three-phase demagnetization. The operation is simple and user-friendly, and even the largest power transformers can be quickly and safely demagnetized using a proprietary algorithm.
