CONVERTER FOR FORMING THE NEUTRAL IN AN ISLANDED SPLIT-PHASE POWER SYSTEM
A neutral forming converter provides a center point neutral reference when a single-phase power source supplies power to a load center in a split-phase power system islanded from the electrical grid. When a load center is islanded and the center-tapped utility transformer cannot provide a neutral reference, a single-phase power source such as a bidirectional electric vehicle charger can supply power to the load center but will require a neutral reference for loads that operate on only half the line-to-line voltage. Without a neutral reference, loads with different impedances can cause the single-phase power system to become unbalanced. The neutral forming converter connects circuitry forming a neutral reference node between the two line voltages of the single-phase power supply. The converter actively balances the voltage between the loads connected across Line 1 and the neutral reference and that between the loads connected across Line 2 and the neutral reference.

To address voltage violations introduced by the extensive integration of DERs into distribution power grids, a voltage control system is provided to maintain the proper voltage levels essential for a stable and reliable distribution power grid. The voltage control system uses a two-stage approach. In the first stage, the system regulates voltage at the local level, typically at the consumer's premises. Local level control relies on the flexibility of various DER systems, such as EV charging systems, photovoltaic systems, and battery energy storage systems, which can be controlled and adjusted to maintain stable voltage levels within acceptable limits. In the second stage, distributed control is implemented by coordinating distributed voltage-regulating devices such as PV inverters, OLTCs, and capacitor banks to control network voltage in real time. The two-stage voltage control system minimizes voltage violations, reduces energy consumption costs, and maintains the stability and reliability of the distributed power grid.

A button assembly may include a TEST or RESET button for a ground fault circuit interrupter (GFCI) outlet. In one example, a dual-layer function button assembly may include an external button configured to receive a manual force to push the external button into the outlet and an external spring engaged with the bottom of the external button. An inner button may be arranged within the outlet, behind the external button, that is connected to components that initiate the associated function. The inner button may include an upper side configured to engage the bottom of the external button such that the external button pushes the inner button into the outlet.
A pressure vessel is disclosed, comprising a pressure vessel body defining interior for containing a pressurized fluid and an accessory attachment structure coupled to the pressure vessel body. The pressure vessel body comprises a liner and at least a first layer that surrounds the liner, the first layer including a fiber-reinforced polymer. The accessory attachment structure comprises an accessory connection portion and an anchor portion. The anchor portion is secured between the liner and the first layer with the first layer overlapping the anchor portion. The accessory connection portion projects outwardly from the anchor portion at least partially through the first layer.
Disclosed herein are electrical outlets having circuit interrupter functionality, for instance, through a ground fault circuit interrupter (GFCI) system. The described electrical outlets include a moveable contact assembly configured to implement the circuit interrupter functionality. In one example, the moveable contact assembly includes a moveable load contact, a moveable receptacle contact, and a moveable arm bifurcated along a lateral plane into a first planar leg and a second planar leg. The moveable load is arranged on the first planar leg and the moveable receptacle is arranged on the second planar leg. The moveable arm may be moveable longitudinally into a RESET state where the moveable load contact engages a stationary load contact and the moveable receptacle contact engages a stationary receptacle contact to place the electrical outlet into normal operating conditions, where the stationary receptacle contact arranged at a different longitudinal height than the stationary load contact.

Disclosed herein are water-resistant housings for an electrical outlet. The water-resistance of the housings is implemented via interlocking step structured connections between sub-housings of the main housing. In one example, a water-resistant housing assembly may include a top and bottom housings each having perimeters formed of outer ridges and inner grooves, and a middle housing having a top middle perimeter and a bottom middle perimeter, the top middle perimeter and the bottom middle perimeter comprising respective inner ridges and outer grooves. In some examples, the middle housing is configured to form water-resistant connections with the bottom housing and the top housing via forming a interlocking step structure between the inner ridges and the outer grooves the corresponding outer ridges and inner grooves of the bottom housing and the top housing.
In one embodiment, a valve train assembly includes a rocker arm having a cam end in proximity to a cam and a valve end opposite to the cam end and in proximity to one or more valves, an engine brake capsule coupled to the cam end, and a cylinder deactivation capsule coupled to the cam end. The engine brake capsule includes an actuation pin assembly, a check valve assembly, and a plunger, and is configured to switch between a retracted position and an extended position. The cylinder deactivation capsule includes an outer body, an inner body, and a latching mechanism, and is configured to switch between a latched position and an unlatched position. In this way, the valve train assembly may perform both engine brake and cylinder deactivation functionalities, for example, at the cam side of the valve train assembly.

ANGULAR STEPPED U-CORE AND ARMATURE PLATE SYSTEM GENERATING INCREASED MAGNETIC FORCE FOR TRIP MECHANISM OF CIRCUIT BREAKER
An improved magnetic trip mechanism for a circuit breaker includes a magnetizable U-shaped core and an armature whose shapes are advantageously designed to increase magnetic force within a compact footprint. In particular, the magnetizable U-core comprises step formations that enable the armature to be received at least partially within the U-core, thus enabling the armature to move a greater distance as compared to an arrangement including a non-stepped U-core while maintaining or decreasing the footprint of the circuit breaker. The arms of the U-core can additionally comprise slanted surfaces in order to further increase the surface area of the U-core and thus increase the number of magnetic field lines and magnetic force generated when the U-core is energized.
The present disclosure pertains to systems and methods for rapid fault neutralization. An apparatus for managing an electrical fault in an electrical system can include a bridging member configured to establish a conductive pathway between contact points that are at differing electrical phase potentials within the electrical system. The apparatus can include a propulsion system configured to cause movement of the bridging member towards the contact points in response to the electrical fault in the electrical system, thereby initiating the conductive pathway. In this way, the apparatus responds to the electrical fault by initiating a controlled electrical arc through the conductive pathway.
