Why you are using on load tap changer in primay of transformer?
The primary windings are bigger In size and it will be more accurate to tap it than tapping the smaller size secondary windings. Answer A tap changer is installed on the high-voltage side of a transformer, regardless of whether that transformer is a step-up or a step-down type. So, it isn't necessarily installed on the primary side of the transformer. The reason for this is that the current on the high-voltage side of the transformer is lower than on the low-voltage side, and the make/break contacts can be smaller. Also there are more turn on the high-voltage side so a finer degree of adjustment can be achieved.
Is it normal for a transformer to buzz?
Sometimes. It depends on the size of the light (watts), the operating voltage, and the line voltage. Very large high voltage lights often buzz.
Calculating appropriate low voltage transformer for outside low voltage lighting?
calculate the total sum of lighting power and add 10% as safe operation of the transformer. then select a transformer for that rating. suppose your total lighting power is 300VA. add 10% of the total lighting power so the total power is 330VA. therefore your transformer size can be 330va or more. please follow IEE regulations.
Why primary side of transformer blown?
It is either a short in (1 or more) of the windings (if its multi-phase) or the applied voltage was too high. What is the application, size (wattage), voltage, a number of phases for this Xfmr? I might be able to help you troubleshoot it further with this information.AnswerIt depends on what you mean by 'blown'! Do you mean the primary fuse has operated? If so, then it's likely the transformer's load has exceeded the capacity of the transformer.
Wire size for a 15 KVA transformer?
Primary : 4 Secondary : 3/0 <<>> To answer this question correctly a voltage must be stated.
What size ground wire for a 30 kva transformer?
The size of grounding wire is based on the amperage output of the transformer. The voltage of the transformer needs to be stated. Without this voltage a calculation can not be made. Amps = Watts/Volts = 30000/?.
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 you understand which side of a transformer is high voltage side and low voltage side?
at high voltage side, current is low. hence the size of conductors is reduced or small. At low voltage side, current is high. Hence the size of conductors is large.

What size of cable wire used for 500 kva transformer 240 volt 3 phase?
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
What is the cable size of 1600kVA transformer?
Cable size is determined by current. You did not provide the current, nor did you include the voltage so that we could calculate the current. Please restate the question, and include either the current or the voltage.

Why are large transformers designed not to have optimum regulation in order for circuit breakers to be within reasonable size?
Transformer voltage regulation and size of the circuit breakers have no direct relation
Can you step up a step up transformer?
Determine the type you need (primary voltage, secondary voltage, power rating in volt amperes - not watts, size, etc.) then check a catalog at an electrical or electronics parts store for a standard transformer meeting your requirements. If you find one and the store stocks it, buy it; if not have them order it for you.If there is no standard transformer meeting your requirements, one would have to have a company that custom winds Transformers design and build it for you. Unless you would be buying in quantity, this will be expensive.
Can you get replacement transformer for an 80 watt outdoor low voltage lighting system?
Transformers are not usually need to run electric lights because they are designed to work on the local supply voltage. Yes, look on the side of your existing transformer to obtain the size of transformer needed. Go to any lighting store and ask for one of the same size or a larger one. Do not get a smaller one as it will not output enough wattage for the connected load.
Is 124 volts TOO HIGH for household wall outlet in USA?
Normal voltage for 120volt outlets is 110v to 130v. It would vary depending on the length and size of the wire to the nearest power company transformer, and the different voltage terminals on the transformer that the power company connects.
