WebSep 15, 2024 · RCDs are truely a good ones in normal use, but in repair style work their protective effect is questionable. The request to ban "all isolation transformers" is a bit hastily written and silly, if someone do read what in example CENELEC HD60364-7-7704 or equivalent IEC parallel publication (60364 section 706) says about them. WebThe principle of operation of the RCD is based on the measurement method. At the input and output, the readings of the currents flowing through the transformer are recorded. If the input current reading is higher than the output, then there is a current leak somewhere in the circuit and the protective device is disabled.

WebHowever, RCD allows the existence of hidden common causes. It outputs a causal graph where a bi-directed arc indicates the pair of variables that have the same hidden common causes, and a directed arrow indicates the causal direction of a pair of variables that are not affected by the same hidden common causes. References WebA residual current device (RCD) works on the principle that in electrical circuits the incoming current is the same as the outgoing current. RCD incorporates a core balance transformer (CBT) having primary and secondary windings with a sensitive relay for instantaneous detection of fault signals.
