Operating principle
When overhead ground wires or electric power transmission towers are struck by lightning, the lightning current flows through the transmission tower and causes a magnetic flux around the tower legs. The magnetic flux induced current is utilized as the power source. The solenoid in the indicator opens the case lid and the red flag and the spring that emerge out of the case clearly indicate the struck point.
