What is a "station" service? Very little in a service needs to be maintained.

I have to be honest. If you have to ask this question it is very likely that you are not qualified for maintain a 480V service/equipment.

The station service I am talking about is for the power generating plant which provides reliable 480V to the station. It has MV to LV transformers, potential transformers, bushings, breakers and so on. Which "station" service were you talking about?

In order to make sure that the station service is working reliably, we need to maintain all the equipment, don't you think? Or are you planning to let everything fail before you look at them?

I have no idea. This is why I asked. The term "station service" is not a common one.

Not at all, but the typical electrical service requires no maintenance really. What you describe is quite a bit more than just a service. Especially in the context of this site.
You have an industrial setting where ONLY qualified people should be working.

So you come to a "Home > Home & Garden > Electrical & Lighting > " message board to ask about this??

I think you need to hire a qualified maintenance electrician who is experienced with the equipment you have on site.

Question, are you in the US or CA? I suspect not.

Stan: I did move it from Electrical Engineering because I though there was more help here.

There is confusion as to what "station" means in your context.

You gave a hint when you mentioned the type of devices to be maintained.

Some devices at the MV level are mechanical and need to be lubercated at whatever the manufacturer reccomends. Some things may have to kept clean.

One of the best tools to be pro-active is a thermal imaging camera and inspections at regular intervals.

Are we basically talking about a "substation"?

All electrical equipment needs periodic maintenance. Check the manufacturers instructions for each piece of equipment for their recommendations.

For more in-depth procedures and standard industry practices, see:

InterNational Electrical Testing Association | Neta World

Maintenance and testing requires specialized equipment, such as Infrared camera, Meggar, DLRO, Hi-Pot, Primary and Secondary Injection equipment, Ultra-Sound Detection, torque wrenches, etc.

Unless on site maintenance crews have access to this test equipment and have the proper training, best to call in a testing firm.

Just to clarify, my original reply was directed at a simple service. NOT something like a power generation plant industrial setting.
Testing and maintenance are ongoing in places like that.
In a residence or small commercial setting very little if any preventative maintenance happens. Typically due to the attitude and budget of the owners.

I just get totally perplexed when someone comes on to an internet message board and asks about such work.

Absolutely a case of "If you have to ask...."

I certainly agree:

All I do is give them an overload of information and send them on their way.
