The JRFS series flexible Rogowski coil current transformer certified UL2808 and UL61010-1 Recognized Components, can monitor AC line current in circuits up to 1000 Vac and nominal currents up to 6000 Amps. 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 panelboards, switchboards and industrial control equipment to measure the current on branch circuits and feeders.
The JRFS series CTs may be used with electric energy meters, like the power meters, or for other current measuring purposes. PQ-RoCoil is different in a few key ways from standard CTs. They do not contain a ferromagnetic core, so they don’t saturate, they have excellent linearity, and they have very 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 1V AC) and low current (microamps or less), so they are safer than ratio CTs.
