Difference between line transformation ratio and transformation phase ratio?
line transformation ratio would be the turns ratio (ie voltage ratio), while the phase transformation ratio is most probably the phase shift introduced by a 3 phase transformer.
What is transformation ratio of distribution transformer It is greater or lesser than unity and why?
If it were 1 then there would be no point in having it there!
Is the transformation ratio constant for a given transformer?
Yes, since it depends on the number of turns on primary & secondary winding.
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
Why not stepup transformer is not used in rectifiers?
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
What is transformation ratio of an electrical transformer - 52k?
The transformer is called a passive device since it cannot generate power. Its input power Ein x Iin. must equal its ouput power Eout x Iout, with the exception of internal power losses in the transformer itself. This equality can be used to derive a relation for the current transformation properties of a transformer, namely,In other words, if the output voltage increases, the output current must decrease proportionately, to keep the output power constant. The quantity Np/Ns is called the turns ratio.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
What transformation ratio?
It is the number of turns of copper wire on one side of an iron transformer core to the number of turns on the opposite side of the same iron transformer core. eg. 100 turns on the primary to 25 turns on the secondary is the ratio of 4:1
What is transformer ratios?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
What is transformer w?
Transformer is a electric device which it can be used for to transfer the ac current one circuit to another i.e. To reduces voltage and without frequency changing. Many types of transformer available in various purpose i.e. Stepup transformer, stepdowntransformer ,autotransformer ,,,,,,,etc answered by arivukkarasu.a
How do you xxplain in a simple way function of stepup and step down transformer?
The function of a step up transformer is to step up the voltage given to it. For eg 11/32KV transformer steps up 11 KV to 32 KV. The function of step down transformer is to step down voltage For eg 420/230 V it steps down 420V to 230 V It does step up or down According to step up or step down ratio called transformation ratio k which equals to K=Ns/Np =Vs/Vp =Ip/Is ie ratios Ns:Np=Vs:Vp=Ip:Is=k Vs=secondary voltage Vp=primary voltage Ns=secondary number of turns Np=primary number of turns Is=secondary current Ip=primary current
