摘要： An elbow arrester with a T-body is disclosed capable of coupling with an apparatus for protection from transient over voltage, and coupling with additional cable accessories, without having to loosen the initial connection with the coupled apparatus. The elbow body of the T-body arrester has a first portion, and a second portion protruding from an intermediate section of the first portion to define a T-body. A receiving feature is located within the first portion extending towards a first end, while a male feature is coupled to a second end of the first portion, opposite from the receiving feature. A coupling fastener is integrally molded into the first portion, providing for an apparatus coupled to the coupling fastener to be decoupled without loosening the connection of another apparatus connected to the T-Body elbow. Further, decoupling the other apparatus does not loosen the apparatus coupled to the coupling fastener.

摘要： Resistors have successfully replaced corona point discharge devices in the control of high voltage gradients, such as those experienced in electrostatic accelerators. An improved resistor for such applications which has a single elongate resistive element, one end of which is mounted on a metal clamp which is adapted to be clamped to the edge of a metal disc of the type used in a supporting column or tube of an electrostatic accelerator. The other (free) end of the resistor is unsupported, but carries a tubular capacitive electrode, which provides, with a cylindrical metal housing which is mounted on the clamp coaxially with the resistive element, a spark gap. The free end of the resistor also supports a light-weight connector, into which or on to which a plug can be inserted or affixed to make an external electrical connection to the resistive element.
