RESIDUAL CURRENT DEVICE (RCD) WITH EARTH CURRENT SENSING |
摘要 |
<p>Safety apparatus is disclosed for use with a load circuit connectable to a power supply via an Active conductor and a Neutral return conductor and including an Earth return conductor. The apparatus comprises means for detecting a difference in load current flowing between an energized Active conductor and the Neutral return conductor; and means for disconnecting the load circuit from the power supply in response to the difference in load current, wherein the means for detecting includes means for sensing a leakage current flowing between the Earth return conductor and the Neutral return conductor. A method of operating a load circuit connectable to a power supply via an active conductor and a neutral return conductor is also disclosed. -H -H 0 C> Co 0 C.) ~t oz~ a _____________________ U, C.)</p> |
