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 the function of step up transformer?
The step-up transformer steps up the input voltage to a higher level so that it can be transmitted over a transmission line using smaller conductors. By the power law, power equals volts times amps, so you can achieve the same power with higher voltage and lower current, but the wire size is based only on current.On the other end, step-down transformers reduce the high voltage back to usable levels.

A transformer is a device used to?
Transformers change voltage and current from the primary side to the secondary side, while keeping the power in equal to the power out (minus losses). Any transformer will increase the voltage applied to the secondary (or low voltage side) to the primary (or higher voltage side).
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

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
Why are transformers necessary?
Transformers are necessary to stepup or stepdown voltage levels so that transmission of power is convenient. without stepup/stepdown voltage level according to our requirement losses will be very high and transmission and usage of power is not feasible.
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 does a step up transformer increase?
Power is normally transmitted at high voltage through step up/step down transformers to minimize the power losses in the transmission lines (this is one reason anyway). Since power loss is equivalent to the resistance of the conductor times the current squared, stepping up the voltage by a factor of two cuts the transmission losses by a factor of (2^2 = ) 4.
Why stepup transformer uses ac?
Confusing question! If it is, why transformers use ac? Then it is, for induction there must be change in flux linkage which is possible with ac which frequently changes polarity. In dc there wont be any change. If que is, why step up is used? There will be considerable voltage drop with distant transmission. For this reason step up voltage is required with step up transformer. Since, in high voltages this drop is negligible or efficient transmission
Does Jones chopper is a stepup chopper?
Jones chopper is known as voltage commutated chopper...it is one type of chopper..
How can you use the machine designed in us 460 v 60 hz in Europe with the voltage 400v and 50 hz the power of the machine is 36 kw?
Obtain the services of an Electrical Engineer 1. BUY OR PROVIDE A STEPUP TRANSFORMER WITH A MINIMUM 50 KVA RATING 2. PRIMARY VOLTAGE INPUT= 400V AND SECONDARY VOLTAGE OUTPUT=460V 3. CHANGING FREQUENCY FROM 60HZ TO 50HZ HAVE THE FF. EFFECT IN THE ELECTRICAL AND MECHANICAL PARAMETERS; A. MOTOR RATED HP OR KW WILL HAVE A REDUCTION OF ABOUT 10% B. MOTOR NAMEPLATE EFFICIENCY RATING WILL HAVE A REDUCTION OF ABOUT 17% C. FULL LOAD RUNNING TORQUE WILL INCREASE ABOUT 8% 4. AFTER THOROUGH ASSESSMENT ON THE EFFECT OR IMPACT OR PRACTICALITY OF APPLICATION-PLEASE CONSIDER ECONOMICS. ANYWAY WE ARE DISCUSSING ONLY SOLUTION BASED ON THE GIVEN SITUATION NOT SOUND ENGINEERING.
