OVERHEAD TRANSMISSION LINE FAULT DETECTION BY USING ARDUINO

Date : Jan 2020 - Dec 2020

<div><p>With rapidly increase in demand for electrical power transmission network are intended to increase in number and get widely spread across the country, this increases the risk of stability of the system if any fault is experienced upon the transmission network. The fault over the transmission lines can cause tripping and line may lead to failure of supply in wide area, this requires the effective protection of these lines. The immediate detection and localization of faults experienced by the transmission lines can help in reducing the maintenance and repair time, and power over the affected lines can be restored quickly to ensure continuity of the supply.</p> <p>This thesis proposes the idea of detection and classification of different symmetrical and asymmetrical short circuit faults such as three phase short circuit fault, double line fault, double line to ground fault and single line to ground fault over a transmission line by implementation of a microcontroller system which is programmed to sense the changes in nominal operating voltage levels, any deviation caused in the voltage level due to fault occurred is characterized accordingly and the circuit breaker is instructed to isolate the faulty section from the healthy network, the voltage sensing inputs are provided from a potential transformers.</p></div>
