摘要： A virtual circuit breaker having an electrical relay and a control circuit, the control circuit including a load and wire protection (“OC”) detection unit, a microprocessor and a driver. The OC detection unit is configured to monitor a power flow and the electrical relay is effective to control it. The driver is effective to cause the relay to stop the power flow upon receipt of a deactivation command. The OC detection unit is effective to cause the driver to receive a deactivation command if the OC detection unit senses that a short circuit condition or an overload condition exists. The microprocessor of the control unit is configured so as to be capable of, at least, receiving input from the OC detection unit and sending output to the driver.

摘要： A system has a power source connected to power access points and at least one environmental control system. A threshold compare device is effective to compare the proportional load on the environmental control systems to a preset threshold. If the threshold is exceeded, unused power access points are disabled. This prevents such access points from placing additional loads on the environmental control systems. Conversely, when the proportional load on the environmental control systems drops below a preset threshold, power can be restored to the disabled power access points. A master control unit can monitor the load on the environmental control systems and either or both the environmental conditions in environment zones or the power loading of the power access points and determine whether to disable unused power outlets.

摘要： Series arcing in wiring is a potentially catastrophic situation that has proven to be difficult to detect reliably with existing methods. This invention allows for the quick and accurate detection of series arcing in an electrical circuit. The method works with AC or DC power sources, and at any voltage or current level. This method will also detect high resistance in a circuit, which is another indicator of a potentially hazardous fault condition. The method compares the voltage at each end of a conductor, and will declare a fault when this voltage exceeds the minimum voltage required to sustain arcing.

摘要： A planar transformer includes a magnetic core having an internal opening. A plurality of high current capacity windings are disposed within the internal opening. These high current capacity windings have a length, a width and a thickness. Each winding is formed as an open loop having adjacent first and second end portions. There is at least one primary winding and one secondary winding. The primary winding and/or secondary winding may be high current capacity windings. A first terminal lead is electrically interconnected to multiple adjacent first end portions and a second terminal lead is electrically interconnected to multiple second end portions. Both the first terminal lead and said second terminal lead have a length, a width and a thickness measured with the thickness being less than either the terminal lead length or the terminal lead width.

摘要： An arc fault detection system senses current flow in a power source branch and in one or more load branches in an electrical system. Over a frequency range divided into a predetermined number of frequency bins, a controller records and tallies the branch having largest magnitude of power spectral density for each frequency bin. The branch having highest total tally is determined to be the branch in which the arc fault occurred and can then safely be isolated from the electrical system.

摘要： An electrical contactor has an arc extinguishing component. The electrical contactor includes a first electrical contact and a second electrical contact that, when the contactor is open, define a gap therebetween. The arc extinguishing component includes a magnet adjacent a first side of the gap and an electrically non-conductive shutter adjacent an opposing second side of the gap. The electrically non-conductive shutter capable of reciprocating from a first position to a second position wherein the first position is outside of the gap and the second position is within the gap.

摘要： An integrated transformer device is provided with both inductive and transformer elements. The inductive and transformer elements are combined within the same device, sharing at least a part of the same magnetic and electrical paths. The integrated transformer device comprises a top core, a bottom core, and a shunt core. A high voltage winding is wound around the bottom core. A low voltage winding is wound around the bottom core and the shunt core. Power semiconductor devices, connected in parallel, form a portion of the low voltage winding and are disposed at a location proximate to the high voltage winding.

摘要： Disclosed are methods and systems to manage and limit, by the development of a flow equalization equation, the amount of total input flow capacity within a network among three or more identical consuming members connected on a common distribution network. An objective of this method, and systems implementing the method, is to minimize the maximum input flow volume, such that, any number of consumers devices may operate at full consumption while other consumers are operating at less than full consumption.

摘要： A power relay is controlled by the presence of Volatile Organic Compounds that are often emitted by outgassing from electronic components during overheat and failure conditions. The relay housing contains a standard power relay of single pole single throw (SPST) or a multi-pole double throw relay depending on the application. A micro VOC integrated circuit is placed within the housing allowing access to ambient air through ports in the side of the relay. Air quality is sampled periodically or continuously as is required by the system to adequately monitor for fault events and, in the event of a fault, latch the relay mechanism OPEN breaking the flow of electrical energy the circuit downstream.
