French term

Schéma à émission de courant

French to English Tech/Engineering Energy / Power Generation Power Station Design
Under a list of "Types of Wiring Diagram", which also includes:
Schéma à manque de tension - which I translated as "Undervoltage wiring diagram" (not sure if this is right either!)

From a proposal for building a Combined Cycle Power Plant.

CONTEXT: Type de schéma:: Schéma à émission de courant :: Dans ce cas la fiabilité du circuit de commande doit être maximale. De ce fait sa distribution sera réduite aux organes essentiels, contacteurs et disjoncteurs MT et B.T., aux électrovannes de sécurité de la turbine, éventuellement aux électrovannes de forte puissance. Ces dernières seront protégées sélectivement.

Thx to all .....

Tony M Nov 30, 2012:
@ Chris I don't think it's a 4-20 mA current loop either (though that is a plausible possibility, I suppose); I've encountered this pairing of terms before in connection with trip units for circuit-breakers, and it seems to be more about some kind of current sensing system...
chris collister Nov 30, 2012:
Not necessarily We seem to be talking about a control circuit, so the control system would need to know the status of the disjoncteurs, electrovannes, etc. As I understand it, these are signal currents, not power currents.
Cyril B. Nov 30, 2012:
doesn't the "MT" in "disjoncteurs MT et B.T." indicate that we're talking about a decent amount of electricity going through? not something small
chris collister Nov 30, 2012:
On due reflection, having read the question properly, and with due deference to the guru, they do seem to be describing an instrumentation current diagram, presumably 4-20mA.
Tony M Nov 30, 2012:
Yes, Chris, but it's a special case here... Just consider a transistor output stage, which may be 'current sinking'; in my view (and in the absence of more complete context), we are talking about a similar situation here — note the use of 'émission'. Here, we are talking about very small currents used for instrumentation purposes, where generally speaking, there is no element of 'power transmission'.
chris collister Nov 30, 2012:
power vs. current? As we all know, a flow of current when associated with a finite voltage implies a flow of power, so for all practical purposes "current transmission" and "power transmission" are equivalent. As Cyril says, it's a cultural thing, and "power" sounds more natural in EN.

Current dispatch [circuit] diagram

or 'current dispatching'?

how about 'schematic'? 'Current dispatch[ing] schematic'
sounds better imo

Hi Steve
'power' definitely sounds better... I think it's cultural, it's often hard for us frogs to drop that 'current' thing :)
'power dispatch schematic' sounds good to me
Note from asker:
Hi Cyril - thanks for your answers. I'm wondering if Power Dispatch Schematic may be more accurate? I get more hits when I search using Power rather than Current - French often seem to use current where we would use power ....
Hi - the source text is notoriously badly written (as the agency admits) so it's a bit of a struggle! :-) Thanks for all suggestions.
Peer comment(s):
neutral Tony M : I don't think I can agree about power; in this situation, it really is current we are interested in; and I think Asker may be getting confused, because I don't think I'd use 'dispatch' here; 'power dispatch' is something quite different...

I think the source text is very poor, possibly a translation already... and that it is 'dispatch' they're talking about
