Research on the Principle of Residual Current Protection Technology Based on Transient Waveform Criterion
The paper uses a magnetic modulation current transformer method to detect transient waveform residual currents containing pulsating DC components and even smooth DC components. At the same time, it uses IIR-based digital low-pass filters to filter the collected signals, which improves Filtering accu...

Summary: | The paper uses a magnetic modulation current transformer method to detect transient waveform residual currents containing pulsating DC components and even smooth DC components. At the same time, it uses IIR-based digital low-pass filters to filter the collected signals, which improves Filtering accuracy. The software design is based on the floating-point DSP-TMS320F28335, which realizes the accurate sampling and analysis of the transient waveform residual current, and the transient waveform residual current detection meets the standard requirements. |
