Lightning and surges can cause serious damage to process automation systems.
The main damages and how to prepare for them are as follows:
Damage from lightning and surges
Damage to electronic components : Overvoltage can destroy circuits or damage insulation.
Data loss and errors : Data in your system may become corrupted or errors may occur.
Shortened equipment life : Repetitive surges can significantly shorten the life of your equipment.
Fire Hazard : In severe cases, overcurrent may cause fire or explosion.
How to prepare
Installing a surge protection device (SPD) :
Role : Protects sensitive electronic components by diverting overvoltage to ground.
Installation location : Install at the entry points of power and communication cables and main circuits.
KS C IEC 61643-11,12,21,22
Regular maintenance : Inspection and replacement are performed according to the manufacturer's recommended cycle, and are applicable to unmanned and manned systems.
We are building an IoT system to monitor surge inflow history and enable AI-based response.
Building a lightning protection system :
Install lightning rods : Dissipate lightning energy safely into the ground.
Strengthen the grounding system : Minimize the grounding resistance value and apply the star grounding method.
By monitoring lightning protection information and grounding information, we can establish damage prevention measures and analyze the cause of accidents.
By securing data, we build an Ai/Big Data system.
Cable and communication line shielding :
Use shielded cables : Prevents external electromagnetic interference (EMI) and lightning-induced voltages.
Install passive filters + surge protectors : Reduce induced and indirect surges and electromagnetic interference.
Install SPDs suitable for sensor protection and various automatic control communication BUS systems.
Regular maintenance :
SPD Function Test : Regularly check the operating status.
Check the grounding system : Check the ground connections and ground resistance values.
Obtaining surge information and accident history data through surge inflow monitoring, and predicting AI-based accidents.
Establish a system that can formulate countermeasures.
Training and manuals available :
Prepare your maintenance staff for emergencies by training them in the use of the latest protective technologies and equipment.
