A Constrained Formulation for Simultaneous Line Parameter Estimation and Instrument Transformer Calibration
Antos Cheeramban Varghese, Rajasekhar Anguluri, Anamitra Pal
The process of calibrating instrument transformers (ITs) has been greatly simplified by using phasor measurement unit (PMU) data since this process eliminates the need for (a) addi…

System-wide Instrument Transformer Calibration and Line Parameter Estimation Using PMU Data
Antos Cheeramban Varghese, Anamitra Pal
Uncalibrated instrument transformers (ITs) can degrade the performance of downstream applications that rely on the voltage and current measurements that ITs provide. It is also wel…
