Description
Description
Introduce

G1 is a USB-sized integrator, could be combined with any model and any size of FRC040, FRC080 and FRC100 series rogowski coils to amplify the output signal. It’s essential to equalize and shift by 90° the output signal from the Rogowski coils. It consists of an active electronic circuit with negligible offset and a good linearity. Flexible rogowski coil with G1 integrator meets customer requirements for different outputs and allows for more interfacing with more measurement devices.

Applications
Measuring devices,lab instrumentation.
Harmonics and transients monitoring.
Very high current monitoring,power quality monitoring.
DC ripple measurement,electric furnace,relay protection.
Features
Output could be amplified to any volt within 3V.
Suitable to measure currents from A to hundreds of kA. 
High linearity.Non-intrusive, no power drawn from the main.
Very useful with large size or awkward shaped conductors or in places with limited access.
Flexible and light weights, exquisite appearance.
There is no danger from open-circuited secondary.
