Transmission line maintenance
(OP)
Can you please help me find documents, references or manuals for effective maintenance of transmission lines? Thanks in advance.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

1. Terminal hotspot test - using thermal scanning, this must be done prior to the maintenace period and if possible with the highest load posible during testing time. Upon learning where the hotspots are probably loose contact are present,etc.
2. Cleaning of dust of insulators - dust are electrical conductors, it produces a hizzing sound if there are so many of it already. Clean the insulators with soft cloth and with water or something that has low conductivity.
3. Vegetation - Trimming of trees and other aliens that may come in close contact to the lines.
4. Most Important - DC power supplies of the SF6 breakers. These are the ones that are forgotten. It may have not tripped for quite sometimes due to no fault. But when time comes the cause of breaker bot tripping is the absence of DC power supply, hehehehe.
5. Others - mentioned and are in the sites u read.
Best regards!!

Aside from hotspot test, do you do also testing on insulators (suspension/strain type, post insulators, polymer type)?
