摘要

Residual current device (RCD) is an effective fault leakage current detection and protection device. The international standard IEC 60755 classifies RCDs into four types in accordance with their sensitivity and the shape of fault leakage current. According to IEC 60755, each type of RCD has its own test procedure and guide for suitable demonstration circuits. Many commercial RCD products cannot me...
