Abstract
The range of application of current transformers in bus differential protective systems is limited by saturation in the transformer cores under fault conditions, which may sometimes result in improper relay operations. It is shown that the addition of impedance in the relay circuit will reduce the relay current under fault conditions so as to increase the range of applications for which standard current transformers may be used.
