Once the SCR starts conducting, no more gate voltage is required to maintain it in the ON state. The minimum current necessary to maintain the SCR in the ON state on removal of the gate voltage is called the latching current. There are two ways to turn it off: Reduce the current through it below a minimum value called the holding current, or
The latching current in less than the holding current. The holding current (hypostatic) for electrical, electromagnetic, and electronic devices is the minimum current which must pass through a circuit in order for it to remain in the 'ON' state. [1] [2] The term can be applied to a single switch or to an entire device. A simple example of ...
low SCR: in case of a short circuit, the current is proportional to SCR, therefore generators with low SCR require less protection and thus are cheaper; low SCR allows shorter air gap and lower excitation field, both decreasing the size (an cost) of the generator; with low SCR the amounts of iron and copper are reduced, lowering the cost; high SCR:
In particular, if the pulse width of the gate current is sufficiently large (generally some tens of microseconds), the TRIAC has completed the triggering process when the gate signal is discontinued and the latching current reaches a minimum level called holding current. Holding current is the minimum required current flowing between the two ...
The term holding current may refer to: Holding current (electronics) is the minimum current which must pass through the device in order for it to remain in the 'ON' state; Holding voltage (physiology), in electrophysiology, specifically while voltage clamping a cell, the holding current is the current that is passed into the cell in order to ...

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").
