Transformer Inrush Current: Why Relays Nuisance-Trip and How to Set Around It
Transformer inrush current explained: why it nuisance-trips relays, typical magnitudes, 2nd-harmonic restraint, and how to set 50/87 to ride it.
Inverter Fault Current Contribution and What It Breaks in Protection
Inverter fault current explained: why IBRs deliver only ~1.1-1.5x rated, how it breaks overcurrent, distance, and directional protection, and what to do.
Electrical Insulators in Overhead Transmission Lines
Introduction to electrical insulators In context of power systems, It would not be wrong if we change the expression to “With greater power comes greater issues” as it is always the case with power systems. Transmission of electrical power with greater stability and less losses has always been a challenging issue for power engineers. But…
