This paper analyses the formation mechanism of the transmission distortion of electronic
voltage transformer, and points out that the integrator will magnify the transient transfer error …

Transient protection has the advantage of ultra-fast operation. However, traditional transient
protection is susceptible to the influences of transitional resistance and the initial fault angle …

Abstract Phase-based Alpha (α) Plane Relaying (APR) scheme has numerous advantages
over the Current Differential Relay (CDR) for transmission line protection. Since the large …

External obstacle detection is a significant task in transmission line inspection and is related
to the safe operation of the power transmission grid. In recent years, unmanned aerial …

In general, conventional differential scheme (CDS) is used for the three-terminal
transmission line protection; however, because of CT saturation under external faults, the …
