Abstract (en)
A gas discharge tube is preheated by means of the main voltage (10, 11) during a time which is related to the instantaneous value of that mains voltage, which value is measured with a measuring device (25). The measuring signal is fed to a microcomputer (24) which determines the pre-heating time in dependance on that signal and ignites the gas discharge tube with extraordinary reliability.
