416PVA meter current transformers

Postby tigersmith » Tue May 29, 2012 9:32 am

Greetings,
I recently received a 416PVA 3 phase power meter. The current transformers I plan to use with this meter are rated: 400A : 0.333V. Will these work?

Hello George:

First of all, the JLD416PVA is a single phase AC power meter, not 3 phase. You need three if you want to monitor 3 phase power supply. Also, "400A : 0.333V" sounds odd to me. It should be ratio on current but not ratio on current vs voltage. The 400A C.T. should be something sounds like "400A:5A" or "80:1". It make more sense.

Without the ratio info, it's not possible to configure the meter to read data correctly. It need ratio in integer number. If you're not sure, may be you should get one of our C.T. like the one 500A: 5A (100:1)

My bad....The 416PVA is one I was going to get for home use. The one I got for work was the JLD3300.
Further research shows the CT's I mentioned will not work. I have the correct 400:5 CT's on the way.
