Flexible current sensors, which are also called Rogowski coil sensors, have a split open core. Workers can set up the rogowski coil sensor while power lines stay live because of this split core design. These sensors can work in many tight small spaces that other sensors cannot fit into. People can use them instead of old-style current transformers (CTs).
Flexible current sensors have several good points that traditional CTs do not have.Because flexible sensors do not reach magnetic saturation, they can measure a wide current range and respond quickly to sudden changes. For short-circuit, surge and heavy-load applications, a properly selected high current sensor can capture both steady operating current and sharp transient peaks while maintaining strong resistance to external interference. People can fix and check them without much trouble. The flexible current sensors also offer many different connection ports that users can pick from.
The flexible coil has a structure that users can bend and open. Workers can place this coil right around cables, and they do not need to cut power or pull apart any wires first. This coil has a small body that does not occupy much room inside electric cabinets, so it works well for many situations where wires are packed closely or spaces are narrow. One single worker can put this coil on or take it off fast.
