摘要： A protection system for an IT electrical distribution system (EDS) has a floating reference conductor and two electrical conductors in the form of an active conductor and a neutral conductor. System includes two input terminals for electrically connecting to an MEN electrical power source that is upstream of system. Two output terminals are electrically connected to an electrical load in the form of an electrical motor for a compressor of an upright freezer display. A motor protection device, in the form of an MCB, electrically connects terminals to allow a supply of electrical power to a motor. The MCB is responsive to a fault signal at a port for selectively electrically disconnecting at least one of the terminals. A sentinel unit selectively generates the fault signal at port in response to the current in conductor being greater than a predetermined threshold.

摘要： A protection system for an IT electrical distribution system (EDS) has a floating reference conductor and two electrical conductors in the form of an active conductor and a neutral conductor. System includes two input terminals for electrically connecting to an MEN electrical power source that is upstream of system. Two output terminals are electrically connected to an electrical load in the form of an electrical motor for a compressor of an upright freezer display. Motor is downstream of the system. A protection device, in the form of an MCB, electrically connects terminals to allow a supply of electrical power from source to motor. MCB is responsive to a fault signal at a port for selectively electrically disconnecting at least one of terminals to prevent the supply of electrical power. A sentinel unit selectively generates the fault signal at port in response to the current in conductor being greater than a predetermined threshold.

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.
