Close-up detail photograph of an industrial electrical motor terminal connection showing thermal failure progression. The image should be shot in extreme macro detail, focusing on a single electrical connection point with subtle early warning signs. Use dramatic side lighting to create depth and texture. Overlay or integrate a translucent thermal imaging gradient showing invisible heat building up around the connection - using vibrant technological colors (electric blues, bright oranges, and reds) that create a sense of innovation and advanced detection. The thermal overlay should have a modern, digital quality with subtle grid lines or data visualization elements. Include depth of field with sharp focus on the connection point and softer background showing additional electrical components. The overall aesthetic should feel like cutting-edge industrial technology documentation, emphasizing the hidden danger and the sophisticated tools needed to detect it. Professional commercial photography quality with rich colors and high dynamic range.
