Protect Your Systems: Key Solutions for Lightning Arrester Failures

2025-03-15 12:58:43

Lightning Arresters are critical for safeguarding electrical infrastructure from surges and strikes. However, even robust systems like Zinc oxide lightning arresters can face issues. Here’s how to address common faults and ensure reliable Surge protection.  

1. Cracked or Flashover-Damaged Porcelain Housing  

A ruptured insulator on your lightning arrester often results from aging, contamination, or voltage stress. Immediate action is crucial: isolate the unit, report the outage, and replace damaged parts with epoxy resin alternatives during clear weather. Regular inspections help catch early signs of wear.  

2. Burnt or Broken Connection Leads  

Loose contacts, undersized wiring, or corrosion can melt or sever arrester leads. Always document the fault, request a shutdown, and replace leads with high-grade, properly sized cables. Tightening connections during routine maintenance minimizes this risk.  

3. Faulty Arrester Counter  

A non-functional counter means you lose vital data on surge events. Notify power dispatch teams, log the issue, and schedule a replacement promptly. Modern counters with real-time monitoring enhance surge protection system transparency.  

Why Do Zinc Oxide Lightning Arresters Fail?  

- Moisture ingress corrodes internal components.  

- Valve plate degradation from prolonged exposure to surges.  

- Pollution buildup causing insulation breakdown.  

Proactive steps like sealing housing gaps, using anti-pollution coatings, and sourcing OEM-grade Zinc oxide lightning arrester parts extend equipment life. Partner with certified technicians for tailored maintenance plans to avoid downtime.
