Abstract: Systems for testing a protective arrangement for an electric power delivery system without disconnecting merging units from a protective device are disclosed herein. For example, an intelligent electronic device (IED) may receive, via a monitoring port, one or more operating measurements of an electrical characteristic of the power delivery system while in an operating mode. The IED may change from operating in the operating mode to operating in a test mode. In the test mode, the IED may receive, via a test port, one or more test measurements that represent measurements of the electrical characteristic. The IED may provide test results based at least in part on the one or more test measurements.

Abstract: Highly quantitative methods for determining the concentration of residual phase transfer catalysts (PTCs) in radiotracer or radiopharmaceutical doses are described. The methods comprise mixing aliquots of the doses that can contain residual PTCs with a sodium and/or potassium salt; extracting a residual PTC/salt complex into an organic phase; and detecting the amount of PTC/salt complex in the organic phase. The detecting can involve visual colorimetry or measuring the absorbance or transmittance of the organic phase when the sodium and/or potassium salt comprises a chromophoric ion, or measuring the resistance of the organic phase. Also described are devices for use in performing the methods.

Abstract: An auxiliary winding circuit board includes one or more auxiliary conductive windings. The auxiliary winding circuit board is positioned at an axial end of a bobbin, and a core leg extends through an opening in the auxiliary winding circuit board. A main conductive winding is positioned on the bobbin. The auxiliary winding disposed on the auxiliary printed circuit board has enhanced voltage-isolation from the main winding positioned on the bobbin, allowing both a high-voltage main winding and a low-voltage auxiliary winding to be located on one magnetic component. The magnetic component is configured for mounting on a printed circuit board for an electronic device such as a power supply. A modular magnetic component apparatus includes a bobbin with main winding assembly and multiple auxiliary winding circuit boards that may be interchangeably mounted between the bobbin and core for desired applications.

Abstract: A component printed circuit board is provided between a magnetic component and a main printed circuit board. The magnetic component includes a device such as an inductor or transformer and includes a bobbin for winding one or more coils and a magnetically permeable core. Terminal pins protrude from the bobbin toward the main printed circuit board and provide electrical connection between the magnetic component and the main printed circuit board. The component printed circuit board includes component vias positioned to accept one or more of the terminal pins allowing the terminal pins to be used for electrical connection to both the component printed circuit board and the main printed circuit board. One or more component traces or shielding layers are disposed on the component printed circuit board. Each component trace provides an electrical connection between two or more terminal pins passing through the component printed circuit board.
