"If you don,t know anything [about traditional relays] ,better keep silent."start studying them!!!

Do some research, independently!

The person you insulted has forgotten far more about relays that you will ever know.

This is what happens when you feed your relays bad moths after midnight.

I'd relay the message, but my list of contacts has currently eroded.

I hope doesn't put a bad crimp in your progress.

reference? Wire you short a few strands?

Nicely done and very informative. I do fear however that the self-imposed knowledge blocks will render such gems superfluous.

I haven’t seen any post by regular members that could be classified as “rude”

Try asking other sites to do you’re homework, you’ll find out just how rude engineers can be.

Define what you mean by "hidden failure" ....... you might get a better answer.

Real failures are never "hidden" - they are visible burnt & damaged equipment.

Sometimes there is no annunciation or operator observation to explain why the system tripped and no detectable damage....that is a failure to deliver ideal continuous power.

I think one hidden failure or problem that you may encounter in traditional relays are the flexibility of these relays when adopting it or employing it in a modern powers system. Since traditional relays has a less functions compare to modern one's also you may want to consider its operating range and coverage in terms of protection zone. Further in terms of space and convenience in installing i think that a lot of traditional relays say 12 relays with a very specific function can be done by a single relay particularly a multifunction microprocessor based relays with lots of embedded function which will save space and time upon installation.
