About Lesson
Installation Practices
-
Lightning Arresters
- Connection: Ensure a low-resistance connection to the grounding system.
- Maintenance: Regularly inspect and test arresters for proper operation.
-
Shield Wires
- Support Structures: Use robust poles or towers to support shield wires above the switchyard.
- Tensioning: Properly tension shield wires to prevent sagging and ensure effective coverage.
-
Air Terminals
- Placement: Position air terminals at the highest points on structures.
- Spacing: Follow guidelines for the spacing of air terminals to create overlapping zones of protection.
-
Grounding System
- Installation Depth: Bury grounding conductors and rods to a sufficient depth to ensure effective current dissipation.
- Testing: Conduct ground resistance tests to verify the performance of the grounding system.
