What do you mean by tapping of transformer?
'Tappings' are externally-accessible electrical connections to the turns of a transformer's (usually high-voltage) winding. This enables the number of turns to be changed, resulting in a change to the transformer's turns ratio and, therefore, to its voltage ratio. Tap changing enables the electricity network company to adjust the turns ratio in response to any excessive voltage reduction resulting from a heavy load.
Is the turns ratio of transformer the same as the ratio of voltages across the transformer.why or why not?
plz give me answer the above question
How do you calculate current on the primary side of a transformer only knowing the turns ratio and the voltage ratio?
The primary current on a loaded transformer depends on the secondary current, which is determined by the load. So, if you know the secondary load current, then you can use the turns ratio of the transformer to determine the primary current:Ip/Is = Ns/Np
How a transformer can be used as impedance matching?
If the line impedance is Z0 and the load is ZL then connect the load using a transformer with N turns ration. N=sqrt(Z0/ZL)
What is the maximum voltage on the secondary side of the transformer?
Transformers come in very many varieties and voltages. Transformers have ratings regarding the electrical power that they are connected to. The most important ratings are voltage, power and current. In general the insulation level and number of windings in the secondary and primary determine the maximum rated voltage, and the size of the magnetic wire that makes up the windings, and mass of the iron core, determines the rated power and rated current. It is the insulation level therefore, that determines the maximum, safe voltage that can occur on both the secondary side and the primary side. The turns ratio between the primary and secondary coils of the transformer determines the secondary voltage with respect to the primary voltage. If the primary coil has 1000 turns, and the secondary coil has 100 turns, the transformer turns ratio (usually designated by the letter "a") is 100 / 1000 = 0.1. If a = 0.1, then if 1000 volts are applied across the primary coil, ideally, 100 volts will be measured across the secondary. Transformers have been manufactured with secondary voltage ratings in the range of millivolts, to 1,000,000 volts.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
What determines the transformer ratio?
Transformer ratio, more correctly turns ratio, is the number of turns in the primary winding divided by the number of turns in the secondary winding.
How do you determine transformer turns ratio if the supply source and load is given?
Transformer turns ratio is the ratio of voltages between two windings. For instance, a 24VAC control transformer that runs on 120VAC will have a turns ratio about 5 to 1.
A transformer with a primary of 1200 turns and a secondary of 400 turns has what ratio?
A transformer primary of 1200 turns with a secondary of 400 turns is a ratio of 3 to 1.
What reference to a transformer the current times the number of turns is called the?
Transformer turns ratio
What is current ratio on a transformer?
It's approximately the inverse of the voltage- or turns-ratio:
What is mean by 2is to 3 turns ratio Transformer what is primary turns and secondary turns?
with an ideal electrical transformer with an input current of 2 amps and an output current of 1 amp what is the turns ratio of the secondary and primary coils
Full form of TTR?
TTR = Transformer Turns Ratio
How much output voltage is there if input voltage from a transformer is 32v?
It depends on the turns ratio of the transformer.
How do you calculate turns ratio for current transformer?
The turns ratio is the number of primary turns divided by the number of secondary turns. This is the same ratio as input current to output current. ie the turns ratio N = I1/I2
What is transformer ratios?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
The ratio of coils on the input side of a transformer to coils on the output side is the ratio of the input voltage to the output voltage?
I think you mean 'turns' rather than 'coils' (a coil is made up of a number of turns). The answer is that, yes, the turns ratio is the same as the voltage ratio, for an ideal transformer.
