Product Overview
Description
Flexible Rogowski Coil
N-L Type rogowski coil
This one rogowski coil can monitor AC currents up to 100KAmps. They can be opened and are flexible for ease of installation around bus bars and multiple conductors.
They are intended for field installation within distribution and control equipment such as panel boards, switchboards
and industrial control equipment to measure the current on branch circuits and feeders.
N-L rogowski coil may be used with electric energy meters, or for other current measuring purposes.
N-L rogowski coil are different in a few key ways from standard CTs. They do not contain a ferromagnetic core, so they will not saturate, they have excellent linearity, and they have every low phase angle errors.
Because they lack a core, it is possible to make them flexible and lightweight. Furthermore, the coil output signal is low voltage (less than one volt AC) and low current (micro amps or less) , so they are safer than ratio CTs. N-L rogowski coil generally require a integrating conditioning circuit, since the output of the coil is the derivative of the actual current.
N-L rogowski coil are very dependent on the uniformity of the winding in the sense coil, making them more sensitive to the position of the conductor(s) being measured in the opening and more sensitive to the magnetic fields from external conductors.
N-L rogowski coil mainly provide high accuracy measurement for power frequency current from 1A to 100kA.

Why choose a flexible rogowski coil from Jiangyin spark
People always ask me, why choose you, give us some reason.
I’m a flexible guy, look at my body, simple to retro-fit, I can be used in the complex env
ironment, look at my body again, light weight, flexible and robust.
I’m a superman, I can big or small. My coil length can between 500px to 5000px, so cool.
I’m a math genius and very sensitive to data, so my accuracy is perfect: ±1%.
I’m from elite school, all of my materials pass the UL Certifications and CE Certifications, and my team founded in 1995, they are the first on produce rogowski coil in china, they are the best in china, and they got some patents, so you can see my quality is competitive
As you know i’, m from china(cheap manpower), so I have a competitive price, (much cheaper than flexible rogowksi coil in Europe and America) I have sold to over 25 countries and can count major international companies, government bodies and research institutions as my customers, so you can see I’m a popular guy.
And I’m very safe-No danger of an open circuit secondary and galvanic isolation, of course my excellent linearity (I have no magnetic materials to saturate)
