Rogowski Coil: A Flexible Power Sensing Solution Beyond Traditional Limitations

Traditional current transformers are often limited by magnetic saturation, narrow measuring range and cumbersome installation, failing to adapt to new power scenarios such as new energy systems, smart grids and industrial frequency conversion. As a new generation of flexible current sensing device, the Rogowski coil breaks the technical barriers of traditional equipment. With a unique air-core structure, it serves as an optimal core accessory for high-precision and full-scenario power monitoring.

Compared with traditional transformers, the Rogowski coil features no magnetic saturation and ultra-high linearity. Without iron core hysteresis loss, it accurately measures tiny currents and ultra-large instantaneous currents with an extremely wide range. It adapts well to complex working conditions such as short-circuit impulse current and harmonic current, avoiding data distortion and measurement deviation. It also delivers fast response and tiny phase error, feeding back real-time current changes to support power protection, energy monitoring and equipment operation.
