CAT 5 cable
CAT 5 cable
(OP)
Hi,
I need to know if there is any standard for usage of CAT 5 cable for transmission of data in the switchyard of the high voltage substations .let's say is it ok to use these kind of media instead of fiber optic cable in the HV and EHV environment for substation automation projects?
thanx a lot.

You'll need to get an equivalent with proper use rating.
Fiber would be better.

Will it be in its own conduit?

There is no significant cost advantage. Fiber media converters (if they don't want to use a switch with fiber inputs) are very cheap and easy to use.
Seems to me, your contractor should be the one providing proof/justification!!

I think we're just saying that fiber eliminates a lot of safety and EMI concerns that you would have with wired Ethernet.

Fiber is a wondrous solution to many problems and whoever is first able to make a usable fiber connection between instrument transformers and relays will probably make a killing. We can avoid copper for digital data, but so far the analog data from the instrument transformers still comes in on copper.

We make a unit that uses conventional transformation and then convert it to digital with a fiber output. Not too many people are interested in it.
In reality, there's no real need to justify going away from how IT's are connected now.

Anyway I expect in few years this will change also.

has some figure which shows what kind of media should be used inside control room and what in the switchyard.
