When a new overhead line is installed for a transformer, the conductor is often temporarily floating before it is fully bonded and grounded. If there are nearby energized lines, their electric fields can induce voltage onto the new line through capacitive coupling. This means the conductor can become energized without any direct electrical connection. As the induced charge builds, it may discharge to nearby grounded metal such as transformer housings, hardware, or tools. This discharge can appea
