SMART FAULT DETECTION IN DISTRIBUTION SYSTEM

Distance relay is mainly used for fault detection in the power system. But it cannot be used below 11kV. Hence an electronic smart energy meter is developed for the detection of the fault in the distribution system. It consists of a fault detection circuit an IoT module. The fault detector senses the presence of a fault and give a command signal to the circuit breaker and also passes these fault signal to the operator. This proposed system will be a perfect solution for three major challenges faced in the distribution sector such as automatic fault isolation, information about the fault to the operator and exact location of the fault. The energy meter is capable of displaying the cost of the unit consumed according to their tariff. The variation in tariff can be controlled by an operator using IoT. The initial cost of the proposed system is comparatively higher than the traditional system. As a long term consideration, the cost of installation can be compensated by reducing the wastage of energy by making the consumer aware of the consumption details.
