    Big Piston Rod- What is it off of?

    When Mint Julep said that the big end was surprisingly small, I was thinking that the small end is surprisingly big......... just shows what I know............nuffink.

    What? a difference?

    Here's another one of those that I believe is just semantics but someone out there may be able to shed more light on this. Is there a difference between a Safety Valve and a pressure relief valve? They both fulfil a similar function but definitions in some cases vary quite significantly. Any...

    Compressed or pressurised ?

    So basically, what you are saying is pressurised is under pressure and compressed is pressurised,ie under pressure. ERRRRRRMMMMMMMMMmmmmmmm Nope sorry..........you have got me there. [3eyes]

    Compressed or pressurised ?

    So it's purely down to semantics then ?

    Cheers Scotty, it's not that I would suggest leaving the decision to the operator,as you know, we operators reactions vary from slow(relatively speaking of course) to non existant, whereas engineers will make the decision only after the event has been thoroughly analysed to death and we are then...

    That would be in reference to Generating plant and /or transformers attached to generating plant. More specifically Turbo Alternators both Steam Driven and also Gas turbines(Not that any of this makes any difference).

    Compressed or pressurised ?

    Anybody prepared to explain the difference between compressed and pressurised? 'Cos as everybody is keen to point out to me, you can't compress a liquid (well you can but not very much). But if we can't compress a liquid, how do we do hydraulic tests on boilers? And please do not be afraid to...

    Negative Phase Sequence anybody? To include Negative Phase Sequence Trip Imminent alarm and philosophy. And if we get any ops engineers interested, preferable reactions to the above. Usual rules apply, preferably in words of one sylable or less. Have fun

    And Now MVaR in words of one sylable or less

    Many thanks gentlemen, you can now stop arguing amongst yourselves (yeah, like THAT is going to happen). I think we can safely say beyond reasonable doubt that the question will remain contentious for some time. Lets face it if you lot can't explain it, what chance do us mere mortals stand...

    And Now MVaR in words of one sylable or less

    There would appear to be quite a few trainee politicians in our midst. What was the original question again? All I know is that it wasn't supposed to be an excuse for an argument on CaPitAl bLEediNg LetTers, how very very sad. Why didn't you just tell me (as I suspected)that there isn't a...

    And Now MVaR in words of one sylable or less

    Here's one for all of you clever electrical chappies out there. Imagine trying to explain MVaRs to a new starter, ie. in the simplest way possible. All analogies welcome (except maybe the horse and barge one). Points may be awarded for creativity but deducted for over technicality. This has...
