    Abstract: This disclosure describes a flash tube potential indicator that indicates whether or not a high voltage line is energized. Rectifiers convert a.c. microamps to direct current to charge capacitors. When the capacitors reach a predetermined voltage level, they are discharged through a photoflash tube. The resultant flash indicates the existence of a high voltage on the high voltage line. The various electric circuit components are mounted in a tubular structure which may or may not be directly attached via a suitable clamp to a high voltage line. In addition, to increase the safety of the invention, barium titanate rods capacitively couple the rectifiers to the high voltage line.
