How to Minimize Faults due to live creatures? 2

[nirajagrawal]

It is observed that faults due to Live creatures such as birds , squirrels , monkeys are increasing at substations & at transmission lines. So let me tell if there are various tecniques to detter these live creatures to build a nest on transmission line , under swichgear etc.?

Gee, we're still at 0 monkey caused outages, maybe we're missing something. ;-);-)

It's a really tough question though, as those little buggers can be very persistent and they're small and agile.

Here Pelicans with their 5 foot wingspans do us in,(well and themselves too!). No good way to prevent it either.

For crawling snakes that sometimes find climbing our towers worth their while, we tried fencing the area with fine-holed nylon nets! Snakes get wedged on net holes, make more entries to other net holes, and they can't get out! Monkeys are too intelligent getting caught by nets, I guess!
We tried sprinkling the area with some sulfur powder to no avail!
Hope this helps.

I was on a substation last summer where ratle snakes were a problem. A fine gage wire cloth was buried on one edge and ran up the chain-link fencing about 24 inches. During constructon the entire site was surrounded by a temporary fabric "snake fence". Our environmental officer issued one or two "Rattle snake alerts" a month, all based on sightings inside the temporary fence.
We were in the reporting area of the hospital that records the highest number of rattle snake bites in Canada.
I see a lot of plastic guards installed on the insulators of pole mounted transformers. They are circular plastic sheet about 12 to 18 inches in diameter. They make it difficult for crawling climbing animals to access the insulators and prevent birds from sweeping their wings directly onto grounded metal.
Cheap and easy to install.

Mr Waross & Burnt2X Thanks for your valuable comments.
Sir , usually Crows are building nest on transmission line towers & some time , they use metal wire as a building material for there nest , this metal wire gives strength to there nest but Tripping may cause to our lines. It is observed that when we remove nest , crows again started nest building activity , somewhere else on tower or on nearby tower.
I heard In india Tata Power Limited having some solutions in practice for this problem. If you know something about that please write me.
IEEE has also issued Guide on the same topic , if someone has read that one , please help me.

There are a variety of products that attempt to keep squirrels off electrical equipment, such as:
