saturable reactor meaning in Hindi

Examples

1. Saturable reactor amplifiers were used for control of power to industrial furnaces.
2. Reset of the saturable reactor usually places a minimum off time requirement on GTO based circuits.
3. Saturable reactors at mains ( line ) frequency are larger, heavier, and more expensive than electronic power controllers developed after the introduction of SCRs.
4. Thus, in principle, a saturable reactor is already an amplifier, although before 20th century they were used for simple tasks, such as controlling lighting and electrical machinery as early as 1885.
5. A voltage source and a series connected variable resistor may be regarded as a direct current signal source for a low resistance load such as the control coil of a saturable reactor which amplifies the signal.
6. Saturable reactors provide a very simple means to remotely and proportionally control the alternating current ( AC ) through a load such as an incandescent lamp; the AC is roughly proportional to the direct current ( DC ) in the control winding.
7. Because the required inductance to achieve dimming varies with the size of the load, saturable reactors often have multiple taps, allowing a small inductance to be used with a large load or a larger inductance to be used with a smaller load.
8. The rate of dI / dt is usually controlled by adding a saturable reactor ( turn-on snubber ), although turn-on dI / dt is a less serious constraint with GTO thyristors than it is with normal thyristors, because of the way the GTO is constructed from many small thyristor cells in parallel.
