Application of Ann Methods for Instrument Transformer Correction in Transmission Line Protection
نویسندگان
چکیده
Current and voltage transformers influence the criterion values measurement particularly during disturbances in the system. Certain construction limitations of instrument transformers may in some cases cause maloperation or substantial delay in tripping of the protective relays. Current transformer saturation and discharging of the capacitive voltage transformer’s internal energy during short circuits on an associated transmission line are the most important phenomena affecting accuracy of the voltage and current magnitude estimation.
