When would a multi-tap Industrial Control Transformer (CPT) be recommended in lieu of a standard unit which has fewer voltages or even just one input and ouput voltage? Multi-tap Industrial Control Transformers are designed to provide stock flexibility for users whose equipment may see many different supply voltages throughout it`s life. Some purchasing agents like to use the multi-tap Transformer so they would only need to stock and purchase one Transformer, rather than two or more. However, that is not usually beneficial for the customer as multi-taps are more expensive, heavier, and larger than standard single or dual input/output CPTs. More often than not, 95% of their business is the standard voltage combination of 480 to 120, the D1 voltage code. As such, the D1 also happens to be the highest volume mover for Square D/Schneider Electric, and is priced to reflect this economy of scale. Thus if a purchaser chooses to only use the multi-tap, they are basing a decision to raise their cost on 95% of their product for only 5% of their business.

Why current transformer is step up transformer? A step-up transformer is a transformer that receives its voltage lower than its output voltage (it 'steps-up ' the voltage). While a step-down transformer is a transformer tha…t receives the voltage higher than the output voltage, thus, stepping down the voltage.

Can a transformer be back-fed or used in reverse? – A specific application that requires stepping-up (increasing) the voltage from the available level to the voltage required by the application. – There is an immediate need in an urgent application that requires a step-up transformer. Typically the step-up transformers are not stocked. – Cost related issues.

What is the function of step up transformer? A transformer's 'transformation ratio' applies, whether it is a step-up, or a step-down, transformer. It is normally expressed as its turns ratio, Ns/Np, where N = number of t … urns. For an ideal transformer, it can also be expressed as the voltage ratio, which is Vs/Vp (where p = primary, and s = secondary).hen the output voltage is higher than the input voltage that is considered a step up transformer. When the output is less than the input you have a step down transformer.

- This article is about tappings in transformers. For other uses, see Tap. A tap is a connection point along a transformer winding that allows a certain number of turns to be selected. This means, a transformer with a variable turns ratio is produced, enabling voltage regulation of the output. The tap selection is made with a tap changer mechanism. Taps inside a power transformer.

Transformer Tap Changer Tuesday, April 27, 2010. Transformer Tap Changer. A tap changer is a device fitted to power transformers for regulation of the output voltage to required levels. This is normally achieved by changing the ratios of the transformers on the system by altering the number of turns in one winding of the appropriate transformer/s.

What is the function of step down transformer? The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers.

Transformer Tap changer The tap changer of the transformer performs this task to change the turn’s ratio. The tap changer basic function is that it removes or connects some portion of the winding to the load side or source side. Tap changer can be located on primary side or secondary side. However it will be placed on high voltage winding side.

- A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. You'll see transformers at the top of utility poles and even changing the voltage in a toy train set. Basically, a transformer changes electricity from high to low voltage using two properties of electricity.In an electric circuit, there is magnetism around it.Second, whenever a magnetic field changes (by moving or by changing strength) a voltage is made.his lower voltage electricity is put into the local electric wires at a substation. The substation breaks the larger amount of power down into smaller pieces at lower voltage. It then is stepped down again and again. Once smaller transformers take that voltage down to usually 7,200, the power leaves this substation.

Alternating Current (AC) Transformers Summary. An AC transformer is an electrical device that is used to change the voltage in alternating current (AC) electrical circuits. A simple transformer consists of a dual electromagnet, where there are two sets of wires wrapped around it for the input and output voltages.C transformers. You can see that DC voltages could not be changed with the configuration of the transformer. This is because the DC current would not be changing the magnetic field the way AC current does. And this was the reason that AC won over DC when electricity started to be used around the world.

Inside a Power-Cube Transformer What you can see here are two windings. The purpose of a transformer is to convert one AC voltage to another AC voltage. In this case the transformer converts the normal 120 volt AC current in your house down to three volts. The 120 volts comes in on the primary winding on the left.

Multimeter A multimeter or a multitester, also known as a VOM (Volt-Ohm-Milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analog multimeters use a microammeter with a moving pointer to display readings. Digital multimeters (DMM, DVOM) have a numeric display, and may also show a graphical bar representing the measured value.
