How many amps can you get from a 500Kva transformer?
To answer this question a voltage must be given.
How many 25 amp bulbs fits 105 watt transformer?
To answer this question a voltage must be given. 25 amps drawn by a bulb seem to be on the high side.
Can you power a 12 volt dc indicator light from a 16 volt ac door bell transformer?
No, the 12 VDC light must have a DC supply and the transformer voltage as well as being 16 volts which is too high, the output is AC.
How do you convert 480v to 120v?
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
How do you convert 3 phase 415 volts to 208 volts and Is there any electrical diagram or photo if using auto transformer?
Changing the voltage is done by using a transformer. These voltages are dangerous and the job should be done by an electrician who knows the safety regulations that must be followed in your country.
Can a high voltage transformer be megged with a megger meter?
No. A megger's output voltage is not high enough to test the insulation of a high-voltage transformer if, by 'high-voltage transformer ', you mean a distribution transformer or power transformer. Instead, a high-voltage test set or 'pressure tester' (e.g. a 'HiPot' tester) must be used, as these produce far higher voltages.
How many amps can you get from a 500Kva transformer?
To answer this question a voltage must be given.
Why current transformer should be grounded?
If there is a short circuit between the transformer's high-voltage windings and its core (or any other metal parts, come to that) the fault will be recognised by the high-voltage supply's protective system, which will quickly disconnect the high-voltage line. For this to happen, the metal parts of the transformer, including its core and metal container, must be earthed or grounded to provide an electrical path back to the source of the high voltage.
Is it necessary to connect a fuse at the secondary side of a current transformer?
Definitely NOT! An open circuit (across a melted fuse for example) on the secondary side of a current transformer is subject to a dangerously-high voltage, so a fuse must not be fitted. The secondary side of a CT must never be open circuited.
How can you tell if a transformer is a set up or set down?
The same transformer can be both. It must be operated at the correct voltage on both windings.
What must be the rms voltage rating of the transformer secondary for the voltage doubler that produces an output of 500 v?
The transformer should provide 144-0-144 v to have a no-load voltage of 500 v dc in a voltage-doubler using two diodes.
How can you step down a 15kv transformer single phase to 220v?
A transformer steps the voltage of an electrical power supply up or down. The transformer must be correctly designed for the voltage and current levels that it is intended for. Only ac can be used with a transformer, which is designed to work at a particular frequency.
Can you put transformers in series to double your voltage?
You can if done carefully. The neutral of one transformer must be set up to be at the positive voltage of the other transformer. This might require an intermediate step transformer that is center tapped (so three instead of 2 transformers).
What happens to the current as the voltage is increased by the step up transformer?
Compare a transformer to a balancing act. Both side need to remain equal.The primary side of the transformer is the supply side and the load is connected to the secondary side of the transformer.The load governs the current of the secondary side of the transformer and the voltage of the secondary side must match the voltage that the load required to operate.The ratio of the transformer will determine what the voltage of the secondary side is as compared to the voltage that has to be applied to the primary.The current of a step up transformer will be higher on the primary side that that of the secondary.Apply voltage and current to this concept and you will see that the transformer will remain balanced.The size of the transformer is always calculated from the secondary side of the transformer and the value is written in VA or KVA where V = voltage and A = amperage. Power factor is also taken into consideration when calculating the size of the transformer to be used.
How can install power transformer?
If you are referring to 'power transformers' used in transmission systems, then the requirements are far too complicated to be answered in this forum. If, on the other hand, you are referring to a 'power transformer' in the sense of a small transformer used to reduce your mains or supply voltage at home, then the volt ampere rating of the transformer must equal or exceed the load requirement. The primary and secondary voltages must match the primary supply voltage and the voltage requirement for the load. Any requirements for earthing (grounding) must be observed.
How can transformer oil be used in transformers with voltage rating above its breakdown voltage?
In this circumstance, the clearance between components at different potential must be increased.
What are step-up and step-down transformers?
A Step Up Transformer is one whose secondary voltage is greater than its primary voltage. This kind of transformer "steps up" the voltage applied to it.The Step Up transformer is designed to increase the voltage from the primary winding to the secondary winding.A Step-Down transformer is one whose secondary voltage is less than its primary voltage. The step down transformer is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer "steps down" the voltage applied to it.The basic equation for stepping up or stepping down the voltageNp/Ns is known as the turns ratio.The induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp) and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np).I to answer basic transformer questions.
