T-218PORTABLE FULLY AUTOMATIC TRANSFORMER DEMAGNETIZER

The T-218 is a fully automatic transformer demagnetization tester which performs three-phase transformer and single-phase and three-phase power transformers demagnetization. Transformer magnetic core demagnetization requires the application of AC current with magnitude decreasing to zero. T-218 provides this AC current by internally changing the polarity of a controlled DC current. During the demagnetization process, the instrument supplies the current at decreasing magnitude for each step, following a proprietary algorithm. The principle of the option is to apply a constant current of alternate polarities to the transformer winding, as per the IEEE 0062 1995 standard.
T-218 has a built-in proprietary algorithm for calculating remanent magnetism after the demagnetization. The instrument measures initial flux before demagnetization, maximum flux during demagnetization, and remanent flux after demagnetization. This feature provides useful information about the state of magnetic core after the demagnetization, and assures user that demagnetization process is successful. it enables safe and efficient power transformer demagnetization.
