Abstract :
A novel saturated time-delay transformer is connected in series with the dc load. The transformer detects and limits overcurrent until the fault has been corrected or the power source removed. This transformer design can be used at any voltage level however, the paper describes it in conjunction with high voltage (HV) circuits. Some design details for such a transformer are given.
