Detecting current transformer Components Detection

A system for detecting the presence of an average dc current component in a load comprising a current transformer 10 for supplying a signal representative of the current, and a comparison means 12 and 13, for example a microprocessor and associated RAM, for comparing values of the current taken at time intervals corresponding to a phase interval of substantially nπ, where nπ is an odd ...

    2018-6-26Fig. 2. The current transformer model [14] drop in a real CT which is saturated. This problem can lead to mal-operation of the protective relays. Therefore, it is necessary to present a methodology for detection and compensation of the CT saturation. 2.2 Analytical denition Fig. 2 shows the current transformer model by us-

  • Current Transformer Saturation Detection Using Gaussian

    2013-2-1Current transformer (CT) saturation distorts the secondary current and in consequence leads to operating delay or malfunction of protection relays (e. g. under reaching of over current relays, overestimation of fault loop impedance in distance relays) . Therefore an appropriate saturation detection method is necessary to maintain the protection
