Chunlong Li · China Measurement & Test · 2010
The formation of induction lightning stroke and its harm for electronic weighing instrument has been analyzed theoretically in this paper.Through the potential protection on sensors,meters and other components,discharge channel of sensor current,multi-stage lightning protection on power supply system,common ground connection and reasonable method of wiring,etc.,the damage of induction lightning stroke can be effectively avoided for electronic weighing instruments.
