3 phase pfc

[toptrics]

Hi all
In order to measure your pefc pscc, you need to test across all 3 line conductors then multiply by 2 record the highest value, this is correct isnt it.

Obviously set your meter to the required tedt i.e line - neutral or line -earth.

The PSCC will be the highest in a three phase installation. Double the highest line to neutral value if your equipment cannot measure between phases.

Each line conductor separately the same method and connections as if you were doing it on single phase, take the highest of the 3 readings, and as you say double it. Job done.

i find its nearer 1.7 times the single phase value , being the pedantic jobsworth that i am lol.

Actually root 3.

Actually, I read that the reason for the x 2 is to allow for the remote possibility of a fault across all three phases, which is closer to 2x PFC of one phase to N or E, than 1.732 x
if I remember correctly it was Geoff Cronshaw on the IET forum. I may be mistaken, but I'm sure I'm not.

whats 0.268 between friends ? ;-)
its enough to blow your face off whatever the final figure lol.

Well...if you leave door open!


edit...

out done by John! hahaha

actually square root of 3.

pedantic superiority restored.

I bow deeply to your (eventual) superior pedantry.

Be warned though, young whipper snapper, you've opened my eagle eyed 'misuse of the apostrophe' eye now!

Here you go then...RIZLA?

 

[Guest55]

nope , you've lost me other than a brand of smoke papers.

 

[Silly Sausage]

Try QI and the real name of rollie papers...

 

[Guest55]

you're still too cryptic to give me a fighting chance.
just freakin tell me or we'll be here all night lol.

 

[Silly Sausage]

Lightweight!

Blame QI for this...RIZLA are actually RIZ made by LA+

Arg...no more, keep looking behind you....

 

[Guest55]
