Recently, power quality (PQ) issues have drawn considerable attention of the researchers
due to the increasing awareness of the customers towards power quality. The PQ issues …

The facility to save multiple setting groups (SGs) within digital overcurrent relays (OCRs) is
to adapt the active setting of the relays to the current topology of the power network …

In the event of a single line to ground (SLG) fault in a non-effectively grounded distribution
network, the faulted current is weak (only a few amperes or less) and the existing devices …

For maintaining security of distance relays, power swing blocking is necessary to prevent
unintended operation under power swings. To be dependable, distance relays must operate …

A new algorithm for synchrophasor estimation is proposed to improve estimation accuracy
under dynamic conditions. The real component of a constantly rotating vector and a low …

In the event of a single line-to-ground fault in a non-effectively grounded distribution
network, reliable detection and isolation of faulty feeders aid in ensuring safe network …

Faulty feeder detection helps ensure the stability and safety of power grids after single-
phase-to-ground (SPG) faults occur in distribution networks. The existing detection …

Fault classification of power distribution cables is essential for tripping relays, pinpointing
fault location, and repairing failures of a distribution network in the power system. However …

Accurately evaluating the fault type and location is important for ensuring the reliability of the
power distribution network. A mushrooming number of distributed generations (DGs) …

A current signal often exhibits dynamic characteristics and contains decaying dc
components when an earth fault occurs under power oscillations. In this paper, a dynamic …
