A Novel Indicator for Failed Surge Arresters Using Low-Melting-Point Alloys
Surge arresters are crucial components of electrical systems, safeguarding equipment against lightning strikes and transient over voltages. However, these devices are susceptible to failure due to the degradation of their metal oxide varistor (MOV) blocks. This degradation can lead to thermal runaway, potentially causing damage to connected equipment. The current approach to addressing failed surge arresters involves the use of Ground Lead Disconnectors (GLDs). While GLDs serve their purpose, they may not always disconnect surge arresters promptly enough, especially in cases of severe degradation. This research presents the development and testing of a new visual indicator designed to detect the rise in leakage current beyond a predetermined threshold, indicating the surge arrester’s impending failure. Unlike GLDs, this indicator does not act as a disconnector but serves as a visual alert, informing electrical engineers and technicians to proactively replace the surge arrester before it fails. The proposed visual indicator offers several advantages, including Early warning by providing a timely indication of surge arrester degradation, allowing for proactive replacement, Reduced risk of damage by facilitating timely replacement, it helps prevent damage to electrical equipment and potential power outages and contributes to a safer electrical environment by minimizing the risk of equipment failure and associated hazards. The newly developed visual indicator represents a significant leap forward in surge arrester monitoring. Its ability to detect impending failure early on allows for preventive maintenance, ensuring the safety and reliability of electrical systems while optimizing operational efficiency. This innovation paves the way for a more robust and resilient electrical infrastructure, benefiting power providers, industries, and ultimately, consumers.
