Why is thermal imaging important in substation maintenance?

Thermal imaging is essential in substation maintenance primarily because it helps detect hotspots and overheating components. In electrical systems, even minor temperature increases can signify potential issues, such as loose connections, deteriorating insulation, or failing equipment. By utilizing thermal imaging, technicians can identify these abnormalities before they lead to significant failures or safety hazards.

This non-invasive technique allows for quick and efficient assessments of equipment conditions, helping maintenance teams prioritize repairs and reduce downtime. It plays a crucial role in preventive maintenance strategies by enabling timely interventions that can extend the life of electrical components and enhance system reliability.

While other options mention aspects related to maintenance, they do not directly contribute to identifying electrical faults or performance issues as effectively as thermal imaging does.
