Abstract
A glow tube output detection device that monitors for light emissions from a legacy glow tube so that the status of the glow tube may be fed to other systems such as supervisory control and data acquisition (SCADA) systems for electric power distribution networks. The monitored legacy glow tubes are connected to the various phases of electrical buses to indicate the presence of high voltage including back feeds.
