摘要：
A gas discharge tube is preheated by means of the main voltage (10, 11) during a time which is related to the instan- aneous value of that mains voltage, which value is measured vith a measuring device (25). The measuring signal is fed to a nicrocomputer (24) which determines the pre-heating time in lependance on that signal and ignites the gas discharge tube vith extraordinary reliability.
