The testing operation of L21 lightning warning system in Hohhot basis earthquake station shows that as lightning coming,the device can alarm in prior and switch power supply auto-matically.It plays a key rule in lightning protection of precursor equipment and is a replacer of manual power-offmeasures to provide security safeguards to protect precursor observation equipment to ensure the normal operation of observation records.
