摘要： An electrical protection device for an electrical load includes a pair of input terminals and for respectively electrically connecting to an active conductor and a neutral conductor of an electrical power source. A pair of output terminals and electrically connects to load. A first monitoring unit is responsive to the load current flowing in conductors and for selectively generating a first fault signal. A second monitoring unit selectively generates a second fault signal. A protection unit operates in a normal state to electrically connect terminals and to terminals and respectively to allow the load current to flow from source to load via device. The unit is responsive to either of the first fault signal and the second fault signal for operating in a protected state to electrically isolate terminals and from terminals and, and prevent the flow of the load current.

摘要： There is provided an integration of the leakage current functions of an RCD and the voltage sensing functions of other prior art protection devices. By integrating the two capabilities into one decision making system/algorithm, and considering the circuits performance in terms of leakage current as it correlated with elevated protective earth voltages (and vice versa), an embodiment is created which is able to “look into” a protected electrical system and make much more precise and discerning decisions on electrical status and probability of unsafe events. The resultant technology attends to the outstanding issues with the prior art technologies as they stand, and provides a protection solution that covers the entire range of electrical power wiring configurations and the practical complexities of modern electrical works.
