Decaying DC (DDC) offset current mitigation is a vital challenge in phasor current estimation
since it causes malfunctioning/maloperation of measurements and protection systems. Due …

Frequency and phase of the power grid, which are critical for reliable control and protection
of grid-tied devices, are generally detected by the closed-loop phase locked-loop (PLL). In …

Fault location algorithms for transmission lines use the parameters of the transmission line to
locate faults after the faults have occurred along the line. Although these parameters can be …

Exponentially decaying DC components are normally found in current signals during a fault
in an electric power system. As these components generally decrease the precision of …

Magnetizing inrush currents are known as the most critical potential threat in maloperation of
the transformer differential protection. Therefore, there is a need to detect the inrush current …

Fault current signals typically suffer from primary and secondary decaying DC (DDC)
components due to the transient response of the power system and current transformer. On …

Differential protection is a widely-used approach for power transformer protection, the
performance of which may be, at times, challenged due to the inrush current and current …

This paper presents a new adaptive method based on the intrinsic time-scale decomposition
(ITD) tool for suppressing the decaying dc component effect on phasor estimation. The ITD …

Differential protection failure in discrimination of inrush and internal fault currents will impose
significant challenges and damages both on the power transformers and power systems. To …

Decaying DC component has considerable effect on both accuracy and speed of
convergence in numerical and digital relays for estimating fundamental phasor. Basically …
