Optical Current Transformer Accuracy Problems and Solutions
2010 Asia-Pacific Conference on Power Electronics and Design, 2010Explain the factors which affect the performance of optical current transformer (OCT) and Solutions. Signal processing measure is the key to the application of optical current transformer. Therefore the signal processing system’s improved method of optical current transformer was introduced, and prospects the future development of optical current ...

Transforming the empirical likelihood towards better accuracy
Canadian Journal of Statistics, 2017AbstractUnder‐coverage has been a long‐standing issue with the empirical likelihood confidence region. Several methods can be used to address this issue, but they all add complexity to the empirical likelihood inference requiring extra computation and/or extra theoretical investigation.

Accuracy of Multivariable Refinable Functions and Two-Scale Similarity Transform
Acta Mathematica Sinica, 2000The paper considers refinable function vectors \(\Phi\) with dilation matrix \(M=\text{diag}(2,2,\dots, 2)\). Let \(m(\xi)\) be a refinement symbol of the refinable vector \(\pmb\Phi\) and let \(\Phi\) provide accuracy \(p\). Then, under some additional conditions, the vector \(\pmb\Psi\) with refinement symbol \[ \tilde m(\xi)=T( 2\xi)^{-1}m(\xi)T(\xi)

The effect of instrument transformer accuracy class on the WLS state estimator accuracy
2013 IEEE Power & Energy Society General Meeting, 2013The measurement chain of the power system consists of various components introducing their associated uncertainty to the measured quantity. Although, it is important to identify and quantify the individual uncertainties of the measurement chain components and consequently the combined measurement chain uncertainty, it is nearly impossible to do this ...

Abridgment of a new high-accuracy current transformer
Journal of the A.I.E.E., 1929This paper is presented for the purpose of describing a new method of compensation, by the use of which the ratio and phase-angle errors of current transformers are materially reduced. There are several similar methods now in use, but these methods possess some undesirable features which are not present in the one described in this paper. By the use of
