A method and system detect fire risk in a building electrical system. The method monitors loads connected to a circuit in real time, distinguishes loads by category (resistive, inductive/reactive, electronic), and utilizes features defined for each load category to recognize when a specific load category is turned ON in the circuit. The method is agnostic of appliance combinations connected to the circuit, agnostic of inherent load behaviors, and distinguishes arc faults from overcurrent faults. The method informs a user when conditions in the circuit will cause a fault, by distinguishing between load categories and between normal and abnormal behavior for each load category. The user can thus proactively prevent the fault from occurring without disrupting the circuit, in contrast with existing approaches where the user only learns of a fault after the fault has occurred and the user has to manually troubleshoot the fault.

The present disclosure comprises a vane pump with hydrostatic pressure plates, or port plates, to axially center a rotor between the port plates. The port plates comprise a pressurization arrangement configured to provide unequal opposing pressures to the rotor when the rotor moves closer to one of the port plates, which provides a net axial thrust to the rotor to move it towards a central position. The pressurization arrangement can comprise circular grooves in the port plates in fluid communication with a high pressure exhaust zone of the pump. Fluid moves from the exhaust zone, through pressurized lines, into the port plates, through an orifice, and into the grooves.

Modular and scalable technique for measurement of der/source parameters for multi-phase and multi-source system for ISE and metering applications
Software-based source voltage parameter monitoring is provided for load centers that include one or more DERs. The software enables a system energy manager (SEM) controller to monitor the relevant source voltage parameters of each DER and other voltage sources to ensure that each DER meets applicable safety standards when connecting to and disconnecting from the utility grid. The software eliminates the need to install off-the-shelf (OTS) chips in hardware used within a load center to communicate the source voltage parameters of each voltage source to the SEM controller. Instead, the software enables an SEM controller to detect the voltage signal output by each voltage source in a load center, and uses a dynamically generated internal control signal that is transformed to a rotating reference frame to detect the RMS voltage, phase angle, and frequency of each voltage source output. Eliminating OTS chips eliminates communication latency and increases system reliability.
