Transmission line maintenance

Transmission line maintenance

Transmission line maintenance

(OP)
Can you please help me find documents, references or manuals for effective maintenance of transmission lines? Thanks in advance.

RE: Transmission line maintenance

And so far you have looked where?  We wouldn't want to waste your time giving you information you've probably already obtained doing basic Google searches, etc.  

RE: Transmission line maintenance

(OP)
dpc, I've already got a site at www.powermaintenance.com. If you have other good references pls share. I need it in my study of transmission lines.

RE: Transmission line maintenance

I'm not sure of references but some maintenance practices are:
1.  Wood pole testing for rot
2.  Testing of steel tower grounding
3.  Visual and infrared inspections by helicopter
4.  Right of Way vegetation control

Thanks a lot everyone. Now I have to do some readings.

RE: Transmission line maintenance

Ive been too in transmission maintenance. Annually we do it. Here are some of our things to do:

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!!

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

RE: Transmission line maintenance

we havent included it. we only clean the insulators. but its nice if we do conduct that too.
