3 Ph Load test in server room

[highjon]

Hi guys
I'm new to the forum, self employed installer.
Recently done my 2391 but now have a customer who wants his server room load tested, 3 phase DB.
The 2391 course didnt cover this obviously, and I have no experience of load / probe test kit.
He is looking to log the load per phase, load on load off.
Can anyone point me to information on what test kit is required and procedure?
thanks
John

Buy a Clamp Ammeter.

Depend if you want to log it over a period of time or if you just want an instantaneous snapshot.
For measuring it over time you would need a datalogger and some CT's around the phase conductors.

Thanks for the replies.
Yeah , he's looking to have it logged over at least a 12hr period.
I have as clamp meter but he is looking for something more exact.
thanks

This from RS would do but at 500 quid it's not cheap.
pico Technology | Test and Measurement | Electrical Test | Energy Monitoring | EL040 Current Monitoring Kit |EL040KIT UK

Or this from CPC VELLEMAN SA|PCS10|DATALOGGER, 4CH | CPC plus 3 CT's would do. Would need a laptop as well but most people have access to one.
Suitable CT's would be something like this Hobut | Process Control | Panel Meters | Current Transformers and Shunts | CT105 Series 3 Phase Moulded Case Current Transformers |CT105F200/5-2.5/1

Hope this helps
