What voltage is used for control circuits?
voltage
What is meant by a primary coil and a secondary coil?
In a transformer, the primary coil is the coil that has voltage applied to it. The secondary coil is the coil that we take voltage from. Transformers are used to step up voltage, step down voltage, or simply to isolate circuits.
Will transformer operate if a battery is used for the input voltage across the primary?
Transformers only work on a.c. This is because it's necessary to have a changing primary current in order to induce a voltage into the secondary winding.If you connect a battery across a transformer, it will not work. Furthermore, if the voltage of the battery matches that of the rated primary voltage, the resulting very large d.c. current is likely to overheat the primary windings and even burn it out.
How do you control high voltage using SCR?
By giving proper gate triggering voltage... it can used to control the high power application like ordinary pn junction diode.
What is the most typical industrial three-phase voltage in Thailand?
The most typical three-phase voltage used in China is 380 V.
What is the voltage is used for industrial purposes?
It depends on the country as to which voltage is used for industrial purposes. In the US, for welding for example, voltage may be 480 volts. The frequency in the US is 60 Hertz.
What voltage is used for control circuits?
voltage
What is used to increase or decrease the voltage across a power line?
The device that increases or decreases the voltage impressed across a power line is known as a voltage regulator. A voltage regulator is a type of transformer where the primary and secondary turns ratio are fairly close; one (primary or secondary) often has a tap changing ability to add or remove several windings, allowing more dynamic control of voltage.
Function of tap chenger in transformer?
The tap changer changes the ratio of primary to secondary windings by physically adding or subtracting windings from the primary or secondary. An on load tap changer (LTC) allows dynamic voltage control, which is important when loading of transformers, and the system in general, varies (if the primary voltage sags, the LTC can be used to increase the secondary voltage so customers don't see this sag).
Why current transformers are used?
1) voltage level up-down2) voltage level down-up3) isolationAnswerBecause transmission would be impossible except at high voltages/low load currents due to enormous voltage drops that would otherwise occur, and these are achieved using Transformers..

What is a vrm used for?
To control the amout of voltage to the processor
What method is used to control the voltage of an aircraft alternator?
Aircraft alternators have an electronic voltage regulator.
What Device used to select amount of voltage in primary coil of step up transformer?
There is no selective device to determine the amount of voltage. A transformer is selected by the voltage available at the site for the primary and the load on the secondary side of the transformer.
Where is a step down transformer used?
Outside your home. It brings the primary voltage down to secondary voltage 120/240
What is the function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
