A shunt is a device that is designed to provide a low-resistance path for an electrical current in a circuit.
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 ...
A zigzag transformer winding is a special-purpose transformer winding with a zigzag or "interconnected star" connection, such that each output is the vector sum of two (2) phases offset by 120°. [1]
In a DC shunt generator, the voltage induced across the armature, V a, is directly proportional to the flux acting across it, The flux in a DC generator is directly proportional to the field current, I f. The critical field resistance is defined as the maximum field circuit resistance (for a given speed) with which the shunt generator would ...
Generator separately excited by battery Self exciting generators Series on left, shunt on right. A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation (generator is therefore self excited).
Shunt reactors are used in power systems to counteract the effect of the line parasitic capacitance, thereby stabilizing the system voltage within acceptable limits. [1] The utility of shunt reactors for voltage control on lightly-loaded transmission lines was examined in a 1926 paper presented at the AIEE by Edith Clarke . [ 2 ]
5-500A – 500 W Glass radial-beam pentode; 5CX1500A – 110 MHz, 1.5 kW Ceramic radial-beam pentode, forced air cooled; 5CX3000A – 150 MHz, 4.0 kW Ceramic radial ...
The Wade-Dahl-Till (WDT) valve is a cerebral shunt developed in 1962 by hydraulic engineer Stanley Wade, author Roald Dahl, and neurosurgeon Kenneth Till. [1] [2] In 1960, Dahl's son Theo developed hydrocephalus after being struck by a taxicab. A standard Holter shunt was installed to drain excess fluid from his brain.
