  2. Silicon controlled rectifier - Wikipedia

    en.wikipedia.org/wiki/Silicon_controlled_rectifier

    A simple SCR circuit with a resistive load. A simple SCR circuit can be illustrated using an AC voltage source connected to a SCR with a resistive load. Without an applied current pulse to the gate of the SCR, the SCR is left in its forward blocking state. This makes the start of conduction of the SCR controllable.

  3. Short circuit ratio (synchronous generator) - Wikipedia

    en.wikipedia.org/wiki/Short_circuit_ratio...

    In a synchronous generator, [1] the short circuit ratio is the ratio of field current required to produce rated armature voltage at the open circuit to the field current required to produce the rated armature current at short circuit. [1] [2] This ratio can also be expressed as an inverse of the saturated [3] direct-axis synchronous reactance ...

  4. Short circuit ratio (electrical grid) - Wikipedia

    en.wikipedia.org/wiki/Short_circuit_ratio...

    Large penetration of the inverter-based resources (IBRs) reduces the short circuit level: a typical synchronous generator can deliver a significant overcurrent, 2-5 [7] p.u., for a relatively long time (minutes), while the component limitations of the IBRs result in overcurrent limits of less than 2 [7] p.u. (usually 1.1-1.2 p.u.). [4] The ...

  5. Short circuit ratio - Wikipedia

    en.wikipedia.org/wiki/Short_circuit_ratio

    Short circuit ratio (or SCR) has multiple meanings: Short circuit ratio (synchronous generator) , a value used to characterize the stability of an electromechanical generator Short circuit ratio (electrical grid) , a metric to characterize the grid strength ("stiffness").

  6. Latch-up - Wikipedia

    en.wikipedia.org/wiki/Latch-up

    In electronics, a latch-up is a type of short circuit which can occur in an integrated circuit (IC). More specifically, it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part, possibly even leading to its destruction due to overcurrent.

  7. Maryland Route 564 - Wikipedia

    en.wikipedia.org/wiki/Maryland_Route_564

    Maryland Route 564 (MD 564) is a state highway in the U.S. state of Maryland.Known for most of its length as Lanham Severn Road, the state highway runs 6.73 miles (10.83 km) from MD 450 in Lanham east to a dead end near a connection to MD 197 in Bowie.

  8. Crowbar (circuit) - Wikipedia

    en.wikipedia.org/wiki/Crowbar_(circuit)

    A crowbar circuit is an electrical circuit used for preventing an overvoltage or surge condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage output (V o ), like dropping a crowbar across the output terminals of the power supply.

  9. Maryland Route 3 - Wikipedia

    en.wikipedia.org/wiki/Maryland_Route_3

    MD 3AB is Old Section MD 3, a 0.185-mile (0.298 km) section of road with two dead ends, connecting to MD 3AA in the middle in Millersville, Anne Arundel County. [ 1 ] MD 3C is the 0.69-mile (1.11 km) section of Benfield Boulevard crossing through its interchange with I-97, between a cul-de-sac west of Najoles Road and ending as the road narrows ...
