3 phase meter questions.

[crewb666]

Hi all, i have a quick question which i hope someone will know. Ive been metering for a year on single phase whole current meters, i have an assesment day thursday for a role installing 3 phase meters. how does the process of installing change? does anyone have a copy of 3 phase intallation process? is there much more involved. i understand you have to check phase rotation but other than that is it pretty much same process?

Many Thanks in advance

Ive done my single phase and 3 phase training, so ill try and help

What normally happens is the DNO put you on a course, and they go through safe isloation procedures, and dead testing with test lamps, proving units, etc, then after that you have an assesment.

There's not much differnet, apart from obviously there's two more phases to check, so phase rotation is also checked and verified.

Hope this helps buddy!
