-Protective systems require a faithful reproduction of primary current on the Current Transformer (CT) secondary side. Saturation is a common problem in a steel core CT. Saturation problem causes dreadful effects in the protection systems. This paper presents a simple solution towards detection and compensation of current transformer saturation problems. This paper describes a method in which C...
Protection systems have vital role in network reliability in short circuit mode and proper operating for relays. Current transformer often in transient and saturation under short circuit mode causes mal-operation of relays which will have undesirable effects. Therefore, proper and quick identification of Current transformer saturation is so important. In this paper, an Artificial Neural Network...
multiple coupled circuit modeling of squirrel-cage induction motors, or winding function approach is the most detailed and complete analytical model used to analyze the performance of the faulty induction motors. this paper extends the above-mentioned model to a saturable model including variable degrees of the saturation effects using an appropriate air gap function and novel techniques for lo...
This paper proposes an algorithm for CT saturation by behavior of distorted secondary current. The purpose of current transformer is to convert the primary current in the secondary circuit in a most accurate way. However, during fault conditions CT gets saturated. Some reasons due to current transformer (CT) can saturate like: attempting to mal operation of CT, heavy burden apply on the seconda...
water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. in clean formations, by applying the famous archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can be calculated. additionally, in shaly sand formations this assumption may not be true as the ion...
The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure multi-segment gate (MSG) CNTFET. Band to ...
