Rogowski Coils

[richard_schwass]

Hi there,

Do any of the metering offer work with Rogowski Coils?

If not (as I suspect) are the intermediate devices that might be able to interface these to a current input?

What about the 0-1volt option "F" on the ION7650 - would this work?

Regards Richard

Richard,

in advanced energy metering there are 2 solutions with our Rogowski U018 coils

a) Enercept EM4200 serie

b) iEM3500 series (A9MEM3555 or A9MEM3565)

[Yut · Accepted solution]

ION7650 NICT is fine you can use 1V or .333V output. See www.magnelab.com.

Hi Yut

Thanks for your comment. Do the meters allow for the phase shift of the rope ct's in the firmware?

Also is 1v or 0.333v best if you had a choice? And is it an AC or DC voltage?

Trust things are well in Thailand

Hi Richard,

The EM4300 series energy meters are equipped with 3 permanently attached Rogowski coils, and communicate with the Com'X 200/210, Com'X 510 or SSL MPM gateway devices via ZigBee.

You can search "EM4300 series on the Schneider website for more information. Search - Schneider Electric

Best regards,

Cesar

Richard, output is AC you can set phase shift using telnet command. I cannot tell what is best it depends on the CT design.

hello Yut,

have you already used this rugowsky coils from magnelab?

i´m looking some information from their web site and seems very nice product.

i have only one point that i need to clear is regarding the starting current with good amplitude and frequency responses.

have you some measurement tests of harmonics results to share with us?

I recommend  the blue one from Universal Technic it performs very well except when current is overload it saturated. We test the Magnelab briefly just to show to customer who own it.
