Automated Transmission Line Fault Detection using Distance Locator

Abstract

Faults play an important role in affecting the reliability of power system. More than 80% of the power system faults occur in transmission sector which badly effect the reliability of supply and causes damage to the system. So, it is compulsory to monitor the transmission lines in normal and faulty conditions and clear the fault as soon as identified. The main aim of this proposed research is to design a circuit which will have a capability of determining the type of fault and exact location of fault. From the results of simulations, it has been concluded that the four types of faults such as L-G, L-L and L- L-G have been detected with their location remotely. Afterwards, transfer its data to the utility mobile phone of the user with the help of GPS and NodeMCU.
