Which test is performed to identify loose electrical connections?

The heat scanning test is specifically designed to identify loose electrical connections by using infrared thermography. This method involves scanning electrical connections and components with an infrared camera to detect variations in temperature. Loose connections often create increased resistance, leading to localized heating. The infrared camera detects these heat signatures, indicating potential problem areas that may not be visible to the naked eye. This non-intrusive method enables electricians to assess connections without disrupting the electrical system, ensuring safety and reliability.

In contrast, while thermal imaging and heat scanning may seem similar, "heat scanning" specifically refers to the targeted approach used for this purpose in electrical applications. A continuity test checks if an electrical circuit is complete and conductive, not specifically revealing loose connections unless they result in an open circuit. Voltage drop tests measure the voltage loss across components under load conditions but do not directly identify loose connections either.
