Fault Simulation and Analysis of High-Voltage Circuit Breaker's Spring Charging Mechanism using a Universal Motor Model

This paper presents a comprehensive study on the fault simulation and analysis of the high-voltage circuit breaker's spring charging mechanism (HVCB-CM) using a universal motor (UM) model. A MATLAB/Simulink model of the spring charging mechanism was developed, allowing for simulations in both healthy and faulty states of UM. The simulations focused on the effects of field winding and armature open circuit faults, providing insights into their impact on the system's performance. The results offer valuable information for training operators and developing AI-based diagnostic algorithms to detect faults in real-time. Overall, this study contributes to the advancement of fault simulation techniques for HVCBs, aiming to enhance system reliability and maintenance practices in power transmission and distribution networks.
