Introduction:
South Africa has one of the highest lightning ground strike densities in the world, which can have major financial repercussions for businesses and home-owners. Lightning strikes pose a threat to borehole installations, including those using DC solar pumps without a grid connection. This article provides practical tips to safeguard your system and prevent damage from lightning-induced surges.
Understanding Lightning-Induced Failures:
Lightning generates massive energy, inducing electrical currents in nearby wires. This can damage pumps, motors, and other equipment in borehole installations.
Preventing Damage:
Install Surge Arrestors: These devices divert excess electricity to the ground, protecting your system from surges. Place them strategically along your wiring. Choose Quality Equipment: Invest in high-quality surge arrestors and protective gear to ensure reliability during lightning strikes.
Optimize Arrestor Placement: Position surge arrestors close to the pump motor for maximum effectiveness.
Use Proper Cables and Ground Connections: Select appropriately sized cables and ensure robust connections to the ground for effective surge protection.
Regular Maintenance: Check surge arrestors regularly, especially after storms, to catch any issues early.
Insurance Coverage:
While it’s essential to take preventive measures, there are no guarantees against lightning damage. Consider insuring your expensive equipment for added financial protection.
Conclusion:
By implementing these measures and considering insurance coverage, you can protect your DC solar pump system from lightning strikes and ensure its longevity.
