  • Fault Detection in Transmission Lines | Grounding in Power System

    Electric System FaultsGroundingWhat Point Must Be Grounded?Grounding in Power TransmissionIn a three-phase power system, a fault, in general, can be a result of a short circuit or an inadvertent open circuit in one or two of the phases. A short circuit can happen owing to physical wear of insulation as a result of age, thermal stress and fatigue, high voltage, high current, harsh environment, abuse, and the like. An open circuit can occur owing to lightning, overload, load surge, malfunction of a device, loss of synchronization, and so on. In either case, there is a significant imbalance between the currents in the three phases. Depending on the severity of a fault, currents of several times magnitude can flow through wires, transformers, and a generator on the power side. If the fault persists, it can cause other failures in a system by overheating and damaging parts, wires insulations, and insulators. In a power system it can cause the fire or in the best situation, if the protective devices act right and cut off the electricity (clearing the fault), a lot of consumers...
