What can the thermal imaging detect in electrical systems?

Thermal imaging is a powerful tool in electrical systems as it can detect temperature differentials that indicate potential failures. The technology works by capturing infrared radiation emitted by objects and converting it into thermal images. In electrical systems, a temperature rise can indicate issues such as overloaded circuits, failing components, or unmaintained equipment. When a connection, terminal, or component generates excess heat due to resistance or a fault, thermal imaging can highlight these hot spots, allowing for proactive maintenance before a complete failure occurs. Detecting these anomalies early helps prevent costly repairs and ensures the reliability and safety of the electrical system.

The other options do not specifically align with the capabilities of thermal imaging. For instance, while environmental hazards may affect equipment, they are not directly detected through temperature readings. Loose wiring connections can contribute to thermal issues, but the imaging itself does not identify the physical connection status. Similarly, thermal imaging does not measure voltage levels directly; it focuses on thermal emission, which is indicative of electrical problems rather than providing a voltage reading.
