Abstract: A method for determining a capacitance value of a capacitor is provided. The method includes receiving a current signal flowing through the capacitor and receiving a voltage signal applied across the capacitor. The received voltage signal and the received current signal are filtered with a low pass filter. The filtered voltage signal and the filtered current signal are then discretized. The discretized voltage signal and the discretized current signal are transformed into a frequency domain. The capacitance value of the capacitor is determined from the transformed voltage signal and the transformed current signal.

Abstract: A system for bulk dispensing an expandable sealant for use in an electrical fitting configured to be used in a hazardous or harsh environment. The system includes a container having a first chamber for holding a first component and a second chamber for holding a second component. An injector is configured to receive the container. The injector includes a first plunger and a second plunger wherein the first plunger aligns with the first chamber and the second chamber aligns with the second plunger when the container is positioned in the injector. A nozzle is configured to engage a distal end of the container. The nozzle is positioned to fluidly communicate with the first chamber and the second chamber when attached to the container. The nozzle has an internal labyrinth passage configured to fluidly connect to the first chamber and the second chamber.

Abstract: A control system includes: a controller configured to: access an estimated torque and estimated speed of a motor mechanically coupled to an impeller of a centrifugal machine; access at least one set of pre-determined performance data values associated with a known speed of the impeller, where each set of pre-determined performance data values includes: a plurality of flowrate values and a plurality of performance metric values; determine an operating point of the centrifugal machine based on the estimated torque, the estimated speed, and the at least one set of pre-determined performance data values; compare the determined operating point to a best efficiency point (BEP) associated with the centrifugal machine; and determine whether to change the speed of the motor based on the comparison.
