Inductive current, a phenomenon often encountered in electrical systems, can lead to significant issues if left unchecked. This phenomenon is characterized by an unbalanced flow of current in the phases of a system, generating an inductive effect that produces heat in unexpected areas. This heat buildup can compromise component integrity, resulting in potential failures and even safety risks.

An example of inductive current is observed in electric motors. If an electric motor experiences phase current imbalances, it can generate inductive currents in its windings. Over time, this can cause localized overheating, leading to insulation degradation and eventually motor failure. Fortunately, infrared thermography becomes an effective diagnostic tool to detect these temperature irregularities.
