1. Technical Principles and Product Innovation: Engineering Breakthroughs in Flexible Measurement
1.1 Scientific Basis of Flexible Sensing Technology
The core technological breakthrough of flexible clamp power meters lies in replacing traditional iron-core current transformers with Rogowski coils. These coils—uniformly wound annular conductors on non-ferromagnetic materials—leverage Faraday’s law of electromagnetic induction for current measurement. Key advantages include:
- Zero magnetic hysteresis
- No magnetic saturation (measures >3000A without distortion)
- High linearity (error < ±2%)
- Wide frequency response (0.1Hz–1MHz)
When current flows through the coil center, the output signal is the derivative of current over time (ε = -M·di/dt). Backend circuits reconstruct the actual current value via integration, enabling milliampere-to-kiloampere measurement.
1.2 Technical Features and Innovations of FR2050 Series
FUZRR’s FR2050 series represents mid-to-high-end domestic flexible clamp technology, optimized for complex field applications:
