Flexible Roche coil current transformer (FCT) can monitor AC currents up to 100kAmps. They can be opened and flexible, making it easy to install around busbars and multiple wires.
FCT-h is a high-frequency flexible current sensor that can be directly combined with portable devices such as power analyzers to form a very flexible system. Suitable for energy consumption monitoring, high-frequency current monitoring, DC ripple measurement, etc. Different sizes can be customized according to requirements.
