Tripping Characteristics of Residual Current Devices Under Nonsinusoidal Currents


This paper presents an experimental investigation into the operating characteristics of residual current devices (RCDs) under an unbalanced current. The unbalanced current included the harmonic current, ground fault current, and surge current. A testing system was first set up in the laboratory, and the minimum values of the current causing RCD samples to… (More)
