Current-Transformer Saturation Compensation for Transformer Differential Relays
IEEE Transactions on Power Delivery, 2015Current-transformer (CT) saturation threatens accurate discrimination between internal fault current and magnetizing inrush current of a transformer and endangers the proper operation of a differential relay. Thus, compensation of CT saturation could substantially improve the performance and security of transformer differential relays.

Fast compensation of current transformer saturation
2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010This paper presents a novel method for current transformer (CT) saturation detection and compensation. In the method, CT saturation characteristics are represented by a partial nonlinear regression model. The parameters of this model can be estimated rapidly and accurately using both unsaturated and saturated sections of the waveform of a secondary ...

Discrete wavelet transform based approach for current transformer saturation problem
2009 IEEE 17th Signal Processing and Communications Applications Conference, 2009This work is about the possible effects of protection devices and schemes during current transformer saturation. If current transformer specifications are not selected properly, saturation may occur and affect relay response or even fail to trip. Hence, the performance of the protection devices such as differential and impedance relays is mainly based ...

Current Transformer Saturation Effects on Coordinating Time Interval
IEEE Transactions on Industry Applications, 2011The primary function of protective devices is to remove faulted equipment from the electrical system. It is typically very advantageous for these devices to isolate as small of a section of the electrical system as possible. Overcurrent protection is the most common protection function used, as faulted equipment typically results in a large short ...

Correction of Saturated Current Transformers Secondary Current Using ANNs
IEEE Transactions on Power Delivery, 2006Current transformers (CTs) provide instrument-level current signals to meters and protective relays. Protective relays' accuracy and performance are directly related to steady-state and transient performance of CTs. CT saturation could lead to protective relay maloperation or even prevent tripping.

Neural network for current transformer saturation correction
1999 IEEE Transmission and Distribution Conference (Cat. No. 99CH36333), 1999Current transformer (CT) saturation can cause protective relay misoperation or even prevent tripping. This paper presents use of artificial neural networks (ANN) to correct CT secondary waveform distortions. The ANN is trained to achieve the inverse transfer function of iron-core toroidal current transformers which are widely used in protective systems.
