Paper Info
This paper introduces a novel arc suppression device designed to mitigate the risks associated with hazardous arcs in power systems, particularly those caused by shunt faults. The device operates by injecting voltage into the neutral line path, a strategy that not only reduces arc currents during fault conditions but also prevents system isolation. The paper provides a comprehensive review of existing arc suppression methods, including both passive and active technologies, and discusses their limitations. It then delves into the design considerations for the proposed device, focusing on aspects such as neutral path selection and voltage injection method. The effectiveness of the device is evaluated through simulations conducted using MATLAB Simulink, revealing that the addition of a device capable of injecting a zero sequence component significantly limits the fault current in the faulty phase. Importantly, the voltage at the load terminal remains unaffected by the device’s addition, making it a low-cost and advantageous alternative to active arc suppression devices. The paper also explores how changing the open delta polarity or transformer ratio does not impact the fault current and discusses practical implementation issues, including cost and compatibility with existing power system components.

Abstract: This paper proposes an arc suppression device to address hazardous arcs caused by shunt faults in power systems. The device injects voltage into the neutral line path, reducing arc currents during fault conditions and preventing system isolation. Existing methods for arc suppression are reviewed, including passive and active technologies, with their limitations discussed. The paper presents design considerations for the proposed device, such as neutral path selection and voltage injection method, and evaluates its effectiveness through simulations conducted using MATLAB Simulink. The results show that the addition of a device that injects zero sequence component significantly limits the fault current in the faulty phase. The voltage at the load terminal is not affected by the addition of the device. The device is a low-cost and advantageous alternative to active arc suppression devices, combining the benefits of passive and active devices while avoiding their negative effects. Additionally, changing the open delta polarity or transformer ratio does not affect the fault current. Practical implementation issues, such as cost and compatibility with existing power system components, are also discussed.
