This paper deals with a quantum algorithm for internal fault detection of a classical electrical system. Quantum computing is growing rapidly, offering many computational advantages along with enhanced security options. In this work, an attempt has been made to resolve a well-known classical problem using quantum computation. A classical system consisting of a multiphase transformer connected with power and load buses has been considered as a system. The objective has been set to detect whether any internal fault has occurred in the system. Though a classical solution exists using a differential protection scheme, here the same problem has been detected using a quantum algorithm. The result and analysis show that the system at healthy and fault conditions can be modeled using a quantum circuit, and together with a quantum algorithm, can be effectively applied to detect whether the fault has occurred internally to the system. Use of quantum computation-based fault discrimination involves less computational complexity. Moreover, the proposed quantum monitoring system can be used for fault detection that inherently offers secure transmission of fault information in quantum states.
