| Abstract: | An MCU-based AC-DC sensitive residual current device （ B type RCD） on the basis of magnetic modulation principle was presented. ARMS compensation algorithm for residual currents based on power frequency and waveform of residual currents was used to improve the detecting precision. It is verified that the RCD can satisfy the requirement of corresponding standards and be able to provide an effective protection against residual currents including residual sinusoidal alternating currents with frequencies up to 1 kHz, residual pulsating currents within a frequency range of 0 - 500 Hz and residual smooth direct currents. |
