Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...
It necessitates the test of surge immunity in electrical or electronic equipment. IEC 61000-4-5 defines test set-up, procedures, and classification levels. In particular, it standardizes the required surge voltage and current waveforms for laboratory testing, with the "1.2/50-8/20 μs" impulse being the most frequently used surge waveform.
Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform.
Surge control products have been used in many industries to protect the maximum working pressure of hydraulic system for decades. Typical applications for surge relief equipment is in pipelines at pump stations, receiving manifolds at storage facilities, back pressure control, marine loading/off loading, site specific applications where pressure surges are generated by the automation system ...
Powerline worker performs maintenance of a lightning arrester on an electrical transmission tower in New Brunswick, Canada. A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device, essentially an air gap between an electric wire and ground, used on electric power transmission and telecommunication systems to protect the insulation and ...
In electrical engineering, a corona ring, more correctly referred to as an anti-corona ring, is a toroid of conductive material, usually metal, which is attached to a terminal or other irregular hardware piece of high voltage equipment.
Exsurge Domine (Latin for 'Arise, O Lord') is a papal bull promulgated on 15 June 1520 by Pope Leo X.It was written in response to the teachings of Martin Luther which opposed the views of the Catholic Church.
The mission of the Coast Guard Reserve is stated in the Reserve Policy Statement issued in 2018: Serving as the Coast Guard's only dedicated surge force the Reserve Component is a contingency-based workforce, trained locally and deployed globally to provide appropriately trained personnel to meet mission requirements within the prioritized focus areas of Defense Operations, Ports, Waterways ...
