Rogowski Coil
A Rogowski coil, named after Walter Rogowski, is an electrical device for measuring alternating current (AC) or high speed current pulses. It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil. The whole assembly is then wrapped around the straight conductor whose current is to be measured. Since the voltagethat is induced in the coil is proportional to the rate of change (derivative) of current in the straight conductor, the output of the Rogowski coil is usually connected to an electrical (or electronic)integrator circuit to provide an output signal that is proportional to the current.
| Model | Category | Advantages | |
| FCT | Normal | Length is up to 20m. Suitable for metallurgy current detection, the detection of leakage current from the super large equipment to the ground and so on. | |
| FCT-A | High accuracy | Accuracy up to 0.2%. Excellent anti-disturbance, temperature drift and stability. | |
| FCT-F | Super flexible | Suitable for irregular conductor detection, such as the detection of S type output end of transformer. | |
| FCT-H | High temperature tolerance | Temperature tolerance: long time for over 150°, short time for over 200°. Can be used in water or oil. | |
| FCT-M | Mini rogowski coil | Diameter of the coil is down to 4mm. Suitable for current under 1000A, and application with a limitation of space. | |
| FCT-S | High sensitivity | Output up to 1V/100A. Suitable for leakage/zero-sequence detection, mA level current detection, low-frequency signal (<5Hz) detection. | |
| FCT-T | Thicker | High voltage tolerance. Not easy to deformation. Suitable for high voltage, high temperature, and outdoor application. | |
