Voltage Rating And Insulation Coordination
The voltage rating of surge arresters should match the system voltage to effectively protect against overvoltages. It is essential to coordinate the insulation levels between the surge arrester and the other equipment in the system. The insulation coordination ensures that the surge arrester can suppress and divert overvoltages without causing any insulation failures. This coordination involves considering the insulation capabilities of transformers, cables, and other components within the system.
Insulator Contamination And Its Effects On Performance
Contamination on insulators can significantly affect the performance of surge arresters. When insulators become dirty or covered in pollutants such as dust, salt, or industrial emissions, their insulation properties may be compromised. This contamination can cause surface flashovers or partial discharges, reducing the effectiveness of surge arresters. Regular inspection and cleaning of insulators are necessary to prevent contamination-related issues and maintain optimal performance.
Installations And Maintenance Best Practices For Surge Arresters
Proper installation and maintenance of surge arresters are crucial for their long-term performance. Here are some best practices to follow:
- Ensure surge arresters are installed at the appropriate distance from the protected equipment, considering the length of connecting cables.
- Inspect surge arresters periodically for any signs of damage or degradation, such as cracks, corrosion, or loose connections.
