RFIZ

Rogowski Coil

RFIZ-AC series coils can be used for single-phase and three-phase measurement applications. The Built-in integration circuit can
simplify the wiring installation, can output 0 to 2V AC voltage and 0 to100mA AC, and the rated input can be selected between 1A~10kA.

RFIZ-DC series coils can be used for SCADA systems and PLC applications. The built-in voltage integrator can simplify the wiring installation,
can output trms 0 to 2V DC voltage, and the rated input can be selected between 1A~10kA.

The RFIZ series are flexible current transformers based on the principle of Rogowski coils, flexible rope
like air coils, which can be connected around the conductor when it is “live”. Compared with traditional
split and solid-core CTs, they are easier to install and measure. With their flexible design and light weight,
they are very suitable for bus bars and irregularly shaped multi-core wiring harnesses. Rogowski coil
technology has low phase shift error, inductance and excellent linearity, while being largely unaffected by
electromagnetic interference and pulsed DC, thus providing high accuracy.
