 Flexible Rogowski Coil With G1 Integrator

Flexible Rogowski Coil With G1 Integrator

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.



FEATURES:

• Output could be amplified to any volt within 3V.

• Suitable to measure currents from A to hundreds of kA. 

• High linearity.

• Very useful with large size or awkward shaped conductors

or in places with limited access.

• Non-intrusive, no power drawn from the main.

• There is no danger from open-circuited secondary.

Flexible and light weights, exquisite appearance.

Notice: 

1. G1 could stand10kA, input current, at most. To gain a better accuracy, you should choose the one close to&a little higher than the one in your system but not too far from it. For example, the max current of system is 1000A, good choices is like 1200A, 1500A, 2000A..., not 10KA.

2. After you define the input current, you could define the output level. For example, input current: 1000A, output level: 333mV. It refers to 333mV output when 1000A.
