In the Austin transformer the primary and secondary windings are separated by an air gap, so that the high voltage on the mast cannot get into the low voltage lighting supply wiring, causing safety hazards. It is named after its inventor, Arthur O. Austin, who graduated from Stanford University in 1903 and who obtained 225 patents in his career.

Feb 06, 2022· Fig. 3: Principle of the pressure relief valve. A pressure relief valve is a safety device used for protecting the system from excess pressure by diverting the flow of fluid back to the tank. During working, the valve is closed by a poppet by the force of a stiff compression spring to stop the fluid flow. The spring force can be adjusted.

Dec 17, 2021· A pressure relief valve (PRV) or relief valve is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system.
